How would you like to pay about $40 for a gadget that makes you jump up and down like a six-year-old hopped up on Pixy Stix to play your Wii games? That's the idea behind the jOG, an accelerometer that connects in-line between the Wiimote and the Nunchuck, making sure you're not having any fun unless you're running in place -- thereby decreasing the amount of fun you could be having otherwise. The little heart-shaped gadget also has a pedometer to count your steps and one particularly brilliant feature that might just make it usable: a button to turn the thing off.
