Although disgusting at first sight, the recently unveiled Mechanical Tumor may in fact be a forecast of future bio-mechanically engineered computers. Created by Japanese artist Mio Lizawa, the artificial tumor (which looks disturbingly like a brain) shrinks and expands depending on the PC's CPU use.

Controlled by a simple air compressor and actuator motor, the contraption looks incredibly realistic and will probably fool most of your non-geek friends into thinking you've taken your digital obsession a little too far. You can see video of the horrid little PC tumor that could here.
