I started writing Vapor Paint 20 years ago (well, was in 2009) Now it's 31 years old.
... here's an old animation from the work screen.
Another frame from the previously mentioned animation.
For the Recycling pavilion at the Taejon Science Expo in 1993, I made a number of animations whihc were used to make an interactive video disk about recycling (with a lot of fantasy in it).
I'll be posting a few frames of this material, re-rendered on my Mac.
