Wow! Add 4 more reasons im afraid to go on the dance floor. I'd give a testicle to own one of those little guys.
Those guys are so cool! However much money was fired at those to get them going, it was totally worth it! I went to a robot show in Osaka last year, it is truly amazing to see things like that in the flesh. Especially the ones playing football, there was a little tournament I watched from the surrounding schools and Unis, amazing stuff.
