I hate to drop a word like electroencephalogram on you on a Friday, but you're looking at one. Designed by researchers at the Interuniversity Microelectronics Centre in Belgium, the headset provides biofeedback by measuring the electric impulses your brain generates when you think or act. It also doesn't need any batteries — it draws power from the temperature difference between your hot little head and the environment. When it's sunny outside and the unit can't get as much energy, it relies on solar panels instead to leech from the sun.

Possible applications for the brainwave-reading headphones include acting as a brain-control device for video games, monitoring drivers, soldiers and workers to make sure they don't get stressed, and making you look like Lobot from Star Wars.
