This "Mechanical Tumour" plugs into your computer, looking very fleshy and realistic. As your computer runs, it quivers and pulses, growing as your computer works harder.
The brainchild of Japanese interactive media artist Mio I-zawa, this thing is flat-out disgusting. I mean, it's certainly well-made, as I guess the whole point is to look like a real, biological entity, but damn. It looks like something out of a Cronenberg film. I'll stick to using iStat Pro to monitor my CPU, thanks. [Mio I-zawa via Pink Tentacle]
