And You Thought Mood Rings Were Kinky

BBC News: "Japanese inventors have devised a gadget to make you prick up your ears - electronic cat's ears.

Strap on the furry headgear, and its ears are programmed to move in ways that reflect the user's inner mood.

Necomimi, as the toy is called, uses sensors to measure brainwaves, and the cat's ears perk up or flatten accordingly."
