"The Power of X" is an incredible kaleidoscopic dance film shot with a giant kaleidoscope and without computer trickery. The film was the opener for last week's TEDxSummit in Doha, Qatar. It was directed by Körner Union for creative agency WE ARE Pi and features choreography by Icouldneverbeadancer. This making-of video shows the elaborate choreography, the 59 foot tall kaleidoscope, and the massive soundstage that were required for the production:
