Strangely enough, I was talking to nzo on another forum yesterday about something totally different, under his real name. Strange, small world.
Actually it wasn't all that different.
We were talking about colorcycling effects. (!!!!!!) I was jokingly making fun of him about the Robotron intermission carpets and calling out his ability with cycling code!
I guess it makes sense that very few people are interested in this stuff so they would congregate in the same places.
