Frustrated with your flaky roll-up dance pad? Intrigued by things with lasers
in them? Alright, we're all in the same boat then. The Laser Dance Matrix (cause it's not really a "pad") was designed to work with any dance game that supports USB input and uses the aforementioned laser technology to register button presses. Breaking the beam = pressing a button. The writeup does not detail how to build one yourself, but they do have a poll asking if there's interest in either purchasing one, either in kit or fully assembled state. Our (imaginary) sources inform us that West Virginia
is interested in placing a rather large order.
