Gregory's ServerSo, @d6 and @kelp made some improvements to the amiga demo and it now runs silky smooth at 60 fps and even includes the ball direction reversal on collision that I had forgotten to implement.

 YEP! The original demo id NOT REDRAW the screen at all. It was bloody brilliant. Lemme see if I can find the write-up someone did on it... @RL_Dane @d6 @kelp OOh you mean the ball data had the rotation baked in the colors! Yes you're right, I remember that. I didn't have it in me to go that far. Also, the uxn screen is super primitive, it doesn't have anything fancy like the amiga ppu. https://git.sr.ht/~rabbits/uxn11/tree/main/item/src/devices/screen.c This was the thread which included a mention of the Amiga boing ball demo and a link to an article on how it worked. It was mind-bending XD https://merveilles.town/@rezmason/110280052366777929 I don't think you could do convincing rotation with only four colors, though? @RL_Dane it'd be super janky, but we could process a new ball asset from the ball data with a gradient. It'd be a bit slower.  This is great! And it definitely brings back memories! The Amiga was a pretty amazing computer at the time. I had a friend who had an Amiga and had it hooked up to an amplifier and speakers. I have fond memories of being a teenager and hanging out, spending hours watching demos and listening to the music and wondering how they coders were able to do such amazing things!
