S5 Dirty Dozen 40mm (quartz)
Arrived this week, thought 40mm would be massive but actually not a bad fit.
Pretty chuffed, tempted to buy more - not sure why. 🤷♂️
Celestial - Interactive Gravity Well Simulator
Celestial lets you explore star systems as a deformable gravity sheet instead of flat orbital diagrams.
The star moves. Planets sit on and ride the surface it bends. You can change the gravitational constant, push a planet, or drop a new body in and watch the whole system respond in real time.
Systems included:
* Our solar system (with a drifting barycentre)
* Alpha Centauri (two moving funnels)
* Kepler-16 (circumbinary planet)
* TRAPPIST-1 (seven worlds inside Mercury’s orbit)
* The classic three-body figure-eight
It’s a proper Newtonian n-body integrator running in the browser, not pre-scripted ellipses. The sheet itself is an exaggerated visual analogy, and the site is unusually honest about what is real and what is drawn that way on purpose.

Two-way voice front-end for Claude Code: multiple personalities that talk to you and to each other.
I've been building Confab for a while and it's finally at the point where I want people who actually live in Claude (especially Claude Code) to tear it apart.
What it is A native macOS notch app for real two-way voice conversation with Claude - not dictation, not a TTS wrapper on top of chat.
You talk out loud, hands-free. A room of AI advisors talks back - to you and to each other - and can hand off mid-conversation.
How it feels - You're on a conference call with multiple specialists. By voice you can:
- Ask Sage (the moderator) to bring in a team
- Pull in one specialist mid-call
- Send someone back to the bench when they're not useful
No keyboard required for the conversation itself.
What's in the box
- 126 specialist personas across 23 function groups (Software, Legal, Finance, Marketing, etc.)
- Sage as moderator
- On-device speech understanding; built-in voices; history stays on your Mac
Cost model (deliberate constraint) No API key. Uses your existing Claude Pro or Max subscription via the Claude CLI. Zero extra per-token cost. That was a hard design rule from day one and shaped everything else.
Requirements
- macOS
- Active Claude Pro or Max
- Claude CLI set up
What I'd appreciate - Break it. Latency, persona quality, handoffs, CLI edge cases, “this is just a gimmick because…”, whatever. Especially if you already live in terminal/Claude Code workflows.
What I learned - Claude has its limits when it comes to voice analysis, bugs, and intuitive design. Fable quotas are precious. Spent ages trying to figure out a voice crackling bug that ended up originating from the TTS engine.
Dogfooding - parts of the product were built using Confab. I was having conversation with the Confab development team, had them introspect the product code, talk to me about improvements, make code changes etc.
Happy to answer implementation questions in the thread.

I made an explainer/promotional video for my side project, AI-Cascade. Does it make sense to you?
Hey guys (and gals)...
I just finished an explainer video for my tool, AI-Cascade. It tracks the second-order economic and financial impacts of AI.
I have watched this edit too many times and completely lost my objectivity. I need fresh eyes from fellow builders to see if it actually makes sense.
The tool, if anyone's interested - https://ai-cascade.logicaleap.com
Any feedback would be appreciated!
Children of Strife - Adrian Tchaikovsky
If you haven't read the Children of Time series yet, consider this your sign.
I'm partway through the fourth book - Children of Strife, and it's everything I love about scifi books: wildly imaginative, funny, genuinely thought-provoking, and still a page-turner.
Few authors can put you inside the mind of something so alien and make it feel this effortless.
Adrian, if you're accidentally reading this - thank you!.

I've been building a free backgammon site with provably-fair dice and free game analysis. Looking for some feedback
I'm the developer of backgammon.logicaleap.com (used to be P2PBG) - a free backgammon site that runs in the browser. No account, no app install, no ads. I'd really value some honest feedback from people who actually play.
What it does right now:
- Online multiplayer: play a friend over a shared link, or use the public lobby to get matched. In-game chat included.
- AI opponent: a neural-net engine that runs locally in your browser, so it works offline too.
- Pass-and-play on one device.
- Provably-fair dice: rolls use a commit-reveal scheme that both clients verify, so neither player nor the server can rig them. Each roll is auditable.
- Free post-game analysis (runs in the browser)
- Shareable replays: any game compresses to a plain link, and the replay plays back on any browser.
The original version relied on WebRTC and public relays for P2P human-vs-human games had some rough edges. I spent the last while making them reliable, reconnects and page refreshes resume the full game (board, cube, score, turn), and added self-correcting state sync.
I'd really appreciate some feedback from the community here -
- Does anything feel off, slow, or confusing, especially on mobile?
- Is the analysis useful and does it match your read of your own play?
- Anything that breaks, hangs, or looks wrong (screenshots welcome).
- Features you'd actually want that aren't there.

I built a tool to share expenses for my friend's flat - sharing in case it's useful
Hey all - not selling anything, this is genuinely free with no account or app to install, so sharing in case it helps.
My friend has housemates kept losing track of rent + utilities + the random "I covered groceries" stuff - someone always ended up doing mental math or chasing people.
So I built a little thing called Tally:
- Make a group (split), share one link with your roommates. That's the setup - no sign-ups, no app store.
- Everyone adds what they paid, it shows who owes whom and it can even give you the fewest payments to settle up.
- Settling hands off to whatever you already use (Venmo/PayPal/etc.) - it never touches your money.
- It's private - expenses are encrypted, so even I can't see what your house spends.
- Works offline, so logging something is instant.
Free, no ads, no premium tier nagging.
Try it here: https://tally.logicaleap.com.
I'm open to feedback on what's missing for your living situation.
Tally: simple, private expense tracker/splitter with zero accounts & no ads or signup
Just shipped Tally [beta].
It's a mobile web app (works as a PWA too) for splitting shared costs – group trips, share houses, dinners, weekends away, whatever.
The big differentiator is there are no accounts at all. You create a split, get a link, and send it to your mates. They open it in their browser and they're instantly in.
No emails, no passwords, no installing anything.
What actually mattered to me when building it:
- 100% private - everything is encrypted end-to-end and the key lives in the link. I literally cannot see your expenses even if I wanted to.
- Completely free. No limits, no ads, no "premium" nagging.
- Works offline - you can add expenses on a plane or in the bush and it syncs when you're back online.
- It just calculates who owes who and lets you settle up whenever.
- Neutral, cross-border, no-fee settlement - country-aware pay hand-off
- Cross-device sync via passkey
Would love some feedback - if anything feels clunky, confusing, or if there's something obvious you wish it did, tell me.
I'm building this myself and iterating quickly.
Try it here: https://tally.logicaleap.com
Heads up: if you open this from the Reddit app it launches in Reddit's in-app browser, which blocks the storage Tally needs to save your splits. You can still have a look around, but "open in browser" to actually use it.
I built Cliff - a tool that shows what your startup equity offer is actually worth
When I was evaluating job offers, I got frustrated with how misleading startup equity can be. The big “X% equity” or “$Y options at $Z valuation” sounds amazing on paper, but after dilution, liquidation preferences, vesting, taxes, and the reality that most startups don’t exit for unicorn money.. the actual take-home is often way lower.
So I built Cliff - an interactive equity decision toolkit that models realistic outcomes.
What it does:
• Turns your offer letter or cap table numbers into a realistic range of what you might actually take home
• Accounts for future dilution, investor prefs, different exit scenarios, taxes, etc.
• Two modes: guided questions (great if you’re new to this) or full control panel if you have the details
• Everything runs in your browser — nothing leaves your device
It’s neutral: doesn’t hype equity as a jackpot or dismiss it as worthless. Just shows probabilities and averages so you can decide.

Inflation Lab - Interactive simulator showing how inflation actually works
I’ve been building Inflation Lab - a hands-on simulator where you can tweak money supply, interest rates, inflation expectations, supply shocks, etc - and immediately see how inflation, unemployment, and purchasing power react in real time.
To highlight the impact of inflation I included a 'grocery basket' that starts at $100 and changes along with inflation to give a feel of 'real-world' impact.
A few one-click presets for actual historical moments:
- 2008 financial crisis
- COVID stimulus shock
- 1970s stagflation
- Volcker disinflation
- Argentina-style hyperinflation
- and a few others
It’s been a fun and interesting way to better understand what's actually driving prices.
No login, no ads, just the model.
Feedback is welcome.
Interactive simulation that shows how echo chambers form (and how bots make it worse)
I built a little web tool that lets you play with the mechanics behind opinion polarization, echo chambers, and network fragmentation.
You adjust sliders for things like:
- How tolerant people are of differing opinions
- Homophily (how much we prefer connecting with similar people)
- Rewiring rate
- Feed bias (how much the algorithm pushes "engaging" content)
- And you can turn on bots too
Think of each dot as a person, and the (tolerance) slider is how open-minded they are. High tolerance means you'll still listen to someone pretty different from you. Low tolerance means you mostly hear people who already agree with you and quietly tune out the rest.
The bots are just accounts that never change their mind and keep pushing one side. The "bots' push" number is how far they managed to drag the average opinion, compared to the exact same crowd with no bots in it. So it's a rough way of asking how much one small, pushy group actually moved everyone.

I built a free tool that tells you whether automation is worth it
I run a small software studio and I kept hearing the same question from clients: should we automate this thing we do every week. Honestly, half the time the answer was no. It either costs more than it saves, or the task changes so often that it is not worth building anything.
So I made a free calculator/simulator for that decision. You enter how often you do the task, how long it takes, the hourly cost, and a few optional details, and it works out whether automating actually pays back, roughly how long until it breaks even, and whether buying an off the shelf tool or just handing it to someone would be cheaper than building.
It runs the numbers a few thousand times so you get a realistic range instead of one confident looking figure, and it will straight up tell you to leave it alone if the math does not support it. No signup, nothing to install.
Would appreciate to know if the default numbers feel right for your line of work, and what task you ran it on.

I've been thinking through this and I want to stress-test it, because it feels too simple and I suspect I'm missing something - sorry for the long post.
Looking for the strongest pushback.
Many people claim housing costs is a supply-demand issue, but I think they're completely wrong - it's a feature of credit expansion (massive inflation).
Houses cost roughly what banks will lend people to buy them. Demand in any meaningful sense is constrained by borrowing capacity, not by what people "want to pay" ... so when credit expands - through lower rates, looser lending standards, dual-income borrowing, longer loan terms etc - prices rise to absorb it.
The usual response is that house prices have increased dramatically faster than groceries (CPI)- so it can't just be inflation.
I think this comparison is nonsensical - CPI measures goods where the supply can "flex".. for example - if demand for tomatoes rises, we grow more tomatoes and prices go down.
House prices don't "flex" the same way. I don't care if my tomatoes were grown in Toorak or in Toowoomba - but I do care if I buy a house in Toorak or Toowoomba.
A house in Toorak and a house in Toowoomba are not the same product - people don't want to buy a cheap house in the bush, they want an expensive house close to the city - and you can't simply grow more inner Melbourne.
So my conclusion is that viewing housing as a supply-demand issue is misguided.
Two-thirds of Australian bank lending is residential mortgages, so the next logical step is to claim that when the money supply (credit) expands, the extra money mostly flows toward goods with inelastic supply. Premium location housing acts as a sponge for monetary expansion in a way that CPI-basket goods don't/can't.
If credit expansion is inflation, but it flows towards assets rather than the CPI basket - this means central banks have been claiming they can tame inflation while in really they have overseen the largest inflation event in modern history - it's just hidden in the sponge.
