If you're of a masochistic bent, you might be looking for some new ways to...um...get some satisfaction from your daily life. If so, I've got the gadget for you: the Kinniku Mouse, a USB mouse that comes with four electrodes that you paste onto your skin. Attach the electrodes to the mouse via the available connector and with every click of the mouse you get a small shock! Whoopee! According to Shiny Shiny, the mouse is really meant for some sort of shock-based stress Therapy (couldn't you tell from the picture?), but I think you might need some shock treatment if you think that's going to work.
