This is as good of a place as any to ask this: Years ago when I envied demoscene programmers I tried to do animation by way of the redefining VGA font table quickly. I never succeeded in getting that to work for any reasonable frame-rate. Is anybody aware of examples of software that did that and were able to achieve a reasonable frame-rate? I'd love to look at the code, even >25 years later, just for fun.
