Inspired by games such as Dance Dance Revolution and the Nintento Wii,  the Motivatrix is a hybrid exercise / gaming machine. In an effort to replace boring traditional workout machines such as the elliptical or stationary bike, the MX9 Workout Master takes the general design of a Dance Dance Revolution arcade machine, and infuses it into a new generation of workout machines. The MX9 has built in arm sensors so it can see your arms flailing about and sensors under your feet so it can pick up on your fancy footwork.  You can even jam out to your own music on the MX9 although it comes preloaded with some tunes of its own. Probably the most interesting feature of the MX9 is the machines ability to connect to the Internet so people can compete against each other virtually, kind of like a fitness version of Xbox Live.   Source: Engadget
