Modified Mandelbrot set at (0.308854751616, 0.025355333413) With a height of 1.3 * 10^(-8). Interactive instance of it available at this messy URL.

This is what I use to make all of the images I post on this subreddit, and if you'd like to try it out, you can find it at:

There have been significant updates since my last post about it a year ago, some suggested by members of this community. Updates include:

• GPU used for faster rendering. This is unfortunately limited to lower zoom levels due to the way GPU processing works.
• There is now a set of example renderings available (the "Examples" tab at the bottom)
• Better, more dynamic UI.
• Rendering parameters can now be shared through the URL (using the Get URL button at the top)
• Colour staggering now uses a bitmask for each primary, allowing more colour variation. This is found under the "stagger" tab in the "Palette" section.
• It now uses indexedDB instead of localStorage to store data. As a result, thumbnails can now be stored locally, speeding up the initial load significantly.

That last one probably affects only me, as I assume I'm the only person who uses it regularly.

I'm still looking for bugs, so if you do try it out, please let me know if you see any.

The area surrounding the Mandelbrot set here is done using XOR and polar coordinates along with a sine function.

This got damaged in a ride a couple of days ago. The chain broke, and the right side of the frame where it connects to the rear wheel got bent as shown in the photos here.

There is a spot that I first thought was broken, but the latter two images here and the feel of it seem to indicate that it's only the paint.

I'm wondering if this is fixable. I can try to bend it back, but don't know if that would be worth my while. Should I even bother, or would it be too weakened after doing so?

I was trying to make an icon and got this when fiddling with the settings. The checker pattern comes from XORing z - c against zi - ci.
I've used that before, but I found this one rather striking.

I just stumbled upon that at my local Independent grocer and had to share. This is by far and away the best salsa I have ever tasted.

My biggest complaint with most salsas is that they're ridiculously vinegary. The one I bought is their Tequila Blanco & Chipotle Salsa and it is shockingly delicious. Smokey, rich flavour, not too tangy, moderate heat (I'm not a heavy spice guy, but I don't like the completely spice free "mild" most brands offer. This one is a gentle heat that dissipates rapidly).

Delicious, and based in Toronto. I'm looking forward to trying their other products.

My renderer has an option to recursively take the displacement of (z, zi) when calculating, and use that as a new coordinate to pass into itself. Weird shapes like this occur on the edges of where the initial count reaches its count limit.

Done using an altered end condition (|z| + |zi| < 4) and recursive calculation from z, zi displacement.
