Ben Hollis and Eva Funderburgh chose an unusual material to house their Arduino in: clay. Glowback, the little creature they’ve created, has nodules on its back made of transluscent porcelain. The porcelain gives off a soft glow in staggered rhythms provided by the super bright LEDs underneath the nodules.
With physical computing being used more and more in fine arts, it’s exciting to see a project such as this one. See Ben Hollis’ site for full documentation.
