Well, the Veachian part comes from turning my last name (Veach) into an adjective. Whenever I'd write a program or something and I'd go to name it, a name like "The Veach Thingie" didn't sound right to me, but "The Veachian Thingie" did.
As for the 64, I chose it because a lot of the titles of Nintendo 64 games (and the console's name itself) seemed to just be a normal title with 64 stuck on the end for the heck of it (Super Mario 64, Pilotwings 64, Wave Race 64, etc). So I decided just to stick the 64 on the end of my nick for the heck of it too. Now that the GameCube's out though, I don't think we have to worry about that anymore.
It's important to note though that there's no space between 'Veachian' and '64'. It's a pet peeve of mine when people refer to me as Veachian 64, heh.
