I think I'd be one of these guys. The R2 Builders' Club builds their own robots that are recreations of and inspired successors to the astromech droids from Star Wars. For those who don't speak fluent dork, R2-D2 is an astromech droid - three wheeled legs, a dome, and an old ARP synth for a voicebox inside a garbage can and you've got yourself an astromech droid.
And to be completely honest, I think this is the greatest little invention waiting to happen. It's like the Roomba only does more than clean your carpet. It can wander down to different departments in your office and give people files (paper files, not electronic - although I guess it could do that too), it could get you coffee, or hell ... it could even brew coffee and then just dispense it. Yes, the work world is waiting for the astromech droid to become a reality. And by "work world" I probably just mean me and the guys at Astromech.net.
Anyway, in the meantime, I can placate myself with action figures. So I did. And now I'm happier.
