That really was a good one, and when I stopped laughing it got me thinking. Here’s a video of a PD patch that sort of reminds me of the Etch A Sketch. It’s running on Zynthian with RPI4. Also works on a RPI3 but it has sluggish reaction to the controls. I did have to install the ‘else’ external on the zynthian to make this run. You can not draw objects, but you can change the shape, size and behavior of the butterfly and the mushrooms. This patch was created a few years back by Jerobeam Fenderson. Once I put on some finishing touches for the Zynthian I will post the patch.
The Zynthian really is a “Swiss Army Knife”
