The Jupiter Mouse is a sphere of wood fashioned into a mouse that you hold in the palm of your hand to control. You move the cursor by adjusting the tilt of the mouse.
The mouse is made out of “Chinese flowering ash from Japan’s rural Gunma prefecture.” Wow, that’s specific! It comes with a matching wooden stand. The click button represents Jupiter’s “famous spot”, which I had never heard of, so really, how famous can it be? (Answer: kind of famous.) To get a feel for how it works, check out this video of someone playing with the mouse.
The kicker: you’re gonna need a lot of cheddar for this mouse. But if you’re feeling flush, go ahead and drop $239 for one at the Japan Trend Shop.
