Ah, yeah. I was looking at the links Arty posted, and saw little icons that looked like paint brushes and glue with a line through them. Seems like you just snap them together. Looks like they're extremely detailed, and it would be kinda hard. Which makes it all the more worth doing, fuck yeah!
I really wish I could get that METAL GEAR REX though. = (
Saw a cool BIG BOSS action figure that I would totally spend 40 bucks on and put on my desk:
Goddamn, that is kickass.
