I created an app called What's Up Ahead and it has live views of the ferries along with some data about sailing times
I think it looks better than the DOT website but that's just my opinion Let me know what you think.
The idea was to collect open source cameras but then I started putting them in order along a driving route and I'm sharing to the Everett subreddit because this is where I'm located so I used a lot of the Everett local data and thought it'd be useful if you're driving over the pass like Leavenworth or Stevens Pass to look through the cameras to figure out where the snows starts this winter or when traffic is going to start getting backed up It's no replacement for Google Maps but I thought it was a fun little project that I just started hacking on.
