Despite it’s title, I don’t think that this Happiness Hat by Lauren McCarthy is very jolly at all. Intended to help one train themselves to smile, it uses a bend sensor to detect if it’s wearer is smiling, and then stabs them with a meta spike (!) if they aren’t. I could easily imagine this being part of the official dress code in some creepy dystopian society. Interesting take on a personal augmentation device, though. [via core77]
