We've all seen the “Dance Dance Revolution” craze and the myriad plastic floor pad knockoffs. Now, Applied Sciences, a company with real scientists, is introducing a laser-triggered "pad" that works with no moving parts (except feet), and only floor to dance on. The player dances between laser beams to any type of DDR game: “Stepmania,” “In the Groove” and “Dance Dance Revolution” itself. A. Smyth (a real scientist) said the reaction to the prototype — from retailers, schools, kids, college students and old fogies — has been overwhelming: "We totally underestimated the response." The first human to test the completed prototype, Smyth explained that the coolest thing about playing it was "the fact that the floor had become the controller. For most people, though, the coolest things are the lasers."
