Yes, the Copper is a very cool thing. I've done insane copper lists with up to 52 splits per rasterline(each split is 8 pixels wide), and then a unique new set of colors for each rasterline. The result is very mesmerizing. It can look like this: https://youtu.be/d1axngYxuuo?t=3m19s https://youtu.be/d1axngYxuuo?t=3m19s and this: https://www.youtube.com/watch?v=fFeHd5hoRyM https://www.youtube.com/watch?v=fFeHd5hoRyM The Copper can also wait for the Blitter to be ready, and the Copper can give the Blitter new instructions and start a new blit. The circle would be complete if the Blitter could blit into the hardware registers for the Copper and other chips, but it cannot. :-( I think the Atari STe Blitter can do that though. But you can use the Blitter to modify the Copper list, so perhaps they together are Turing complete?
