@avibryant immediate drawing to the screen, self discoverability, structural editing. It's all great ideas. If I was a programming teacher, perhaps I'd use something like ST to show logic in real time and explain procedural graphics.

Uxn is just a CPU, most of the programs that I've built on it are of a much smaller scale, I'm not smart enough with these things to put together something like ST, but I think I can draw inspiration from it and bring some things over.
