In February we completed the “New Prototype Kittolith” and debuted it at the Space Cat Cavalcade. This 5′ tall Catolith was printed by Re3D in Houston, Texas. The sound and lights were created by Theremin Barney, Artur Pyrogovskyi, and Aaron Winette. In this video I am demonstrating the motion detection based sound/light interactivity that Barney engineered using passive infrared sensors. The cat itself is a speaker. A kind of transductive speaker is affixed to the perimeter wall of the cat statue and the entire plastic cat vibrates to produce the sound. The sounds are solfeggio tones that Artur programmed in a randomized cycle to be triggered by the voltage signal transmitted from Barney’s motion detection circuit. This is still a work in progress, but we are developing this system to be used in the ring of six Catoliths that will be installed at Patricia’s Green.
