I'll share one of mine as well. It's a 1-d cellular automata simulator that randomly generates rules and tries to use nice colors. Click to see a new one, and the URLs it generates can be shared. However, that is the limit of interactivity (for now, it's actually meant to be a loose clone of Wolfram Tones but that is far from ready).
I like how space key also works and how browser navigation is supported so that when I accidentally click too many times, I can use the browser's back and forward buttons to navigate between recent patterns.
Sorry for the late response, I'm not used to not getting notifications for responses to my comments.
There is no simple way to get the rules for that CA. However, if you press Shift+Space, you get an alternative representation of the hash that lets you re-seed while keeping the same rule: https://skulk.org/cell1d/#c2:3:1,0,0,1,0,0,1,0:12;120;115,15...
This format is ad-hoc, but you can read it as such: The first number after #c is 2, which is the number of states. The second number, 3, is the size of the transition window. This tells us that this is a standard 1-d CA. The next 8 (2^3) numbers is the transition table. Interpreting it as binary (in reverse), we get the number (and rule) 73. http://atlas.wolfram.com/01/01/73/
The next couple of numbers are the colors used, and the final number is the seed. You can change this and the rules/colors will remain the same but the top row is re-randomized.
The basic mode is a matrix of identical tiles spinning at different rates, creating complex organic motion out of a simple concept. There are two other modes and lots of fun parameters to play with!
This was sadly so much more immersive when the music and sound were available, but the creator removed them due to bandwidth costs. The sounds are still available if you're willing to decompile the ios app and do some spelunking in the Wayback machine; the code isn't all that hard to follow to get audio reenabled
Yeah, as it stands, I wouldn't call this "generative". It is just a nice looking symmetrical drawing demo. I think I played with a similar toy in 1987 or so on a Mac Plus.
This is cool. I once made an app in the same vein [1]. I think that generative/immersive art software has a lot of potential. A large part of making art is enjoying the process, whereas most digital art software is about getting results efficiently.
It's a pretty digital brush but hardly generative. Calling the output generative art is like calling a melody played by a single preset synthesizer running through a delay unit generative music.
There seems to be an interest in generative are on Hacker News lately. Another one I saw that didn't make it to the front page was No Paint:

This has been going to years. By chance I found an old link to it recently and was amazed it was still going. At least Bit Rot doesn't get everywhere (yet)
Some other fun "art toys" I like are:
