Foot power used to control mouse
Now this is definitely one mouse that you won’t want to loan out to others – the Foot Controlled Mouse. This self-descriptive device gives the game away, requiring you to use one foot to move the mouse about while the other takes control of various programmable buttons, including both left- and right-clicks, double click, and scroll functionality. This would make a pretty expensive gag gift at $199 a set, and it will help those who suffer from arm injuries to spend their time recuperating in the hospital while surfing the Web with their feet.
