Inventgeek has just posted their latest project: an industrial strength dance pad. It’s built out of 14GA 1″ steel tubing and acrylic. I brains are from a generic set of DDR pads. There is also a separate lighting system. The pad was built it for an Xbox, but they’ve got a USB adapter for use with Stepmania as well. Although the construction looks really solid, [jared] is careful to mention that this is just the first prototype. It definitely looks better than anything you could buy or find in the arcade.
