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.
