Cepheid is a wooden kinetic sculpture named after pulsating stars. Its curvy, ray-like forms slice and meld into each other as they spin and rock in a seemingly random motion. As Cepheid is set into motion by its spring and magnetic escapement mechanism, it creates a unique visual display of dancing shapes and mesmerizing patterns.

The sculpture is spring powered and uses a magnetic ratcheting escapement, which allow the it to get a “kick” from the spring at any orientation. On a full wind, this piece will run for about 1.5 hours.

A video of Cepheid in motion can be seen here:

This is a fantastic new sculpture! First thought: totally useless and so much fun to watch! Ha, so it’s not useless for sure!
I am a big fan of all your kinetic sculpture. No customer until now, but I bookmarked your website…

This is a very nice piece and a real eye catcher.

As with your other works, this is lovely. Definitely on my wish list to build someday, will keep an eye on your site and plans. The reversing motion is intriguing.

Impressive and a joy to watch. Your wood art is great. Do any of these do perpetual motion? Continue on until you stop them? Thanks for sharing all these great pieces.
