headspace | Magic Wave

This comes from haha.nu.

On 27.11.2008 the Swiss Science Center Technorama opened a show that illustrates three characteristics of waves: wavelength, amplitude and frequency, using a 25-square-meter “magic carpet” that was made of more than 50,000 pieces. Here to the higher quality version. It was created by Reuben Margolin, and staff.

It's not very impressive until it really sinks in: this is not a computer-generated animation... this is an actual live show, on stage, for an audience.
