Wirebrushing/Buffering:
Start off with a fine grit buffer or rotary wire brush, and with either an angle grinder or a hand drill and go to town. If you are doing it by hand, a random pattern looks the best. Although if you have a milling machine and want a pattern, put a really fine wire brush in there, and come down and make circles on your part every X inches to make a regular pattern.

Yes, I should have mentioned that we do go for some "natural" finishes, mostly just polishing, however. We've got one team member, who I'll call "Mr. Bling" who is the king of the polishing wheel. We've got lots of shiny aluminum on our machine.
We've also worked with bead blasting for a matte finish, and on our mini-sumo robots that we make in class we'll even mask off the area to be blasted so that we can polish, then mask and blast to get nice graphics without painting.

P.S. Art... was going to +ve rep you for that great post with all the images earlier on, but have to share some around first.
Gracious Professionalism is being embarrassed at an event by an underperforming catstrophe of a robot, yet standing and applauding for every award because you realize that as hard as you worked that season, the other team must have worked even harder to get their achievements. - Taylor [more]
