Personal Energy Orb Arduino project knows you haven’t been exercising, cripples your computer

This funny, yet slightly cruel hack keeps you pedaling by using the Energy Orb ambiant information device mounted on a bike to inform the user when they have or have not been exercising enough by changing from green to red.  Exercising adds value to some metric, changing the orb green.  Not exercising depletes the value, and the orb eventually turns red.   At this point the controlling application sends a message to your personal computer to slows down the mouse tracking speed, making it more difficult to use and more likely that you’ll go outside and pick up your bike again.
