Thought I'd share this link to a neat interactive art piece.
Interactive media artist Mio I-zawa’s “mechanical tumor” is a hunk of fleshy, organic-looking material that quivers and grows depending on the amount of stress your computer is experiencing.
PS anyone see any DC micro air pumps @ ax man recently? I am thinking about making a "bio-mechanical" element to a steampunk outfit for Halloween. I've thought about a syringe hooked to a linear actuator, but thats kinda bulky.
