Well, there's a collaboration at Brickfair this time around, and I think I'm gonna participate.

Here's the basic idea: There are COGs and REBs (rebels) facing off against each other. COGs are black and red and are supposed to be the upper-class bots. REBs are supposed to be lower-class working force revolting against the COGs. They have a more rusty/old-style feel and should have some kind of function that was used to help the humans, like mining tools.

For more info, here are Primus's, LO's, and Felix's blog entries about it.

Feel free to join in!
