It appears that the exercise gadget the Gamercizer made to PC Magazine’s Top Ten List of Fitness Gadgets for 2007.  This gizmo is actually a joy stick for operating your Nintendo and other games that is powered by your treadmill, cross trainer, cycle or stair climber. The minute you stop exercising your video game fun blips off of the screen. 

Of course the Gamercizer only really suits people who are good multi-tasking as it involves exercising and playing video games at the same time.  If you have a couch potato for a child this could help motivate him or her get off of the couch and start exercising.
