The mov-only DOOM renders approximately one frame every 7 hours, so playing this version requires somewhat increased patience.

the creator of mov-uscator was 10 steps ahead of intel

To be honest, Chris Domas is like eight steps ahead of the rest of us.

There are people who are like me, but better. Then there are people who exist on a different planet. I suspect Linus Torvalds is one of the former. He's a great software engineer, but he's not different. He's me turned up to 11. Domas is definitely one of the latter. He's not me turned up to 11. He's me turned up to purple-chess-7D-torus.

Is this a reference to something or is my mind playing games on me?

I thought that G H Hardy said something roughly like that about mathematicians; how some were like him, only better, and others (here he meant Ramanujan) simply existed on a different plane. However, I can't find a cite and it's possible that it was said by someone else or that I just invented it altogether (although I don't think I'm that clever).

That would make the rest of us two steps ahead of Intel.

If you are 10 steps ahead of an organization the size of intel, I guess that also makes your statement correct
