JediPimp and I were playing his mod, The Jedi Mod, when he decided to crank up the speed to like 5000000000. Well, the speed was so high, that when we ran, we literally 'ramped' off of objects and fly really high in the air...this usually brought us OUTSIDE the level, or let us get ontop of buildings that are usually too high to get to. Anyway, we were on Omaha, and we went 'underground' and happened to find the name of a mapper/developer or something. It's a first name, and being a former CS fan, i can see how mappers like to leave their marks outside/inside the levels. Take a look:
