This music is so metal -- but probably not in the way you're expecting.
A visitor to innovation-centered Maker Faire in New York City came across this incredible display of iron dust dancing to music on Saturday. Artistically-inclined tech company TechnoFrolics engineered the performance.
TechnoFrolics says the dust's "dance" is made possible by computer-choreographed electromagnets beneath the display's platform, and the combined effect of the pulsing techno-art performance is pretty mesmerizing. Just try and look away.
