Human Kaleidoscope Will Blow Your Mind [VIDEO]

I don't know how they pulled this off, but I do know I can't stop watching.

An ad agency in Amsterdam called We Are Pi, put together this amazing video for something called the TEDx Summit which took place recently in Dubai. Using several human models and strategically placed mirrors, the video mimicks the effect of the kaleidoscopes we all played with as kids except, other than zoooming out, the camera never moves. The models move through a synchronized routine to mimick the effect of turning a kaleidoscope.

I'm not sure how long it took to shoot this, but with so many moving parts all required to go through the motions fluidly, I'm pretty sure it took more than one take.
