An intro written for, and partly at, the 1991 Party.
works even with 286/10/VGA/SB!
The most interesting part of this intro in my opinion is the fact that it uses a 16-colour display mode, but it uses tightly synchronized code to swap the palette a few times per frame. The donut is rendered asynchronously in the background, at whatever framerate the CPU can achieve, while the palette changes and scroller are updated every frame.
On C64 and Amiga this is rather common, since these systems have hardware interrupts or the copper to synchronize to the raster beam. A PC does not have this functionality, making it more difficult to achieve the same effect.
