It almost looks as if the video is simply reversed. Via University of New Mexico: This apparatus allows for the visual examination of… READ THE REST

Keyboards and mice are fine for surfing the web. They're fine for working in spreadsheets, assembling a text document or for sorting through emails. But when users need precision control, the old keyboard and mouse often don't quite cut it anymore. For gamers, they turn to souped-up joysticks with a host of extra buttons and… READ THE REST
"Build a better mousetrap, and the world will beat a path to your door." That century-old quote from Ralph Waldo Emerson (sort of) is just as true today.
