Thanks to Our 2009 Foldplay Valentine's Day Kaleidocycle Spokesmodels

Okay, Orelia and Carey didn't know they were going to be the 2009 Foldplay Valentine's Day Kaleidocycle Spokesmodels, but they were really good sports about it, and they did get a couple of free kaleidocycles out of the deal. Carey was also our "hand model" for the photos of the finished product.

Unfortunately, foldplay.com went down on Valentine's Day and stayed down for about 12 hours, due to a hardware failure at our hosting service. Grrrrrrr..... We're apologize to all the lonely hearts who were unable to get to the site.

The Endlessly Rising Scale Meets the Endlessly Rotating Kaleidocycle

The sound track features an auditory illusion appears to rise endlessly in pitch, mimicking the visual motion of the kaleidocycle. The ever-rising sound is described in detail at the wikipedia article on Shepard tones.

Music composed by codename: octave.
