@ The Denver Mini Maker Faire!
The Loveland CreatorSpace was there!
Along with some robots and logic gates, a bunch of 3-D printers, and other stuff of that nature.
And this dog leg brace company (thinking of Duncan Madog and his ACL)
A few other ideas
SteamPunk is big here, some 1950’s electromechanical devices, your maker faire t-shirts and any number of mad scientist clubs.
and of course, The Cardboard Challenge
I mean, if you can’t at least make a cardboard robot costume, what good are you?
