To have a bicycle-like contraption under your desk that you have to pedal to keep your monitor/screen lit. It could have different gears for challenge and variety. It could be called a Screen Master or a Moniped or something. This handy device would keep your blood flowing and allow you to burn some googling calories. It could even store up energy in a battery for later use. Plus: all the folks who obsessively cruise online dating sites and Myspace would get better bodies. Maybe we wouldn't want this at work tho.... somebody call Ron Popeil!
