Here's a ceramic radio that's controlled by touching the palladium patterns on its surface.

Named Hibou (it means Owl, in French), it is the work of two French designers named Celia Torvisco and Raphaël Pluvinage, who worked with a gilder at Paris' Museum of Ceramics on the project. They've worked with tactile interfaces before, so the same principle is applied with Hibou. Each decorative pattern controls a different behavior: control the volume by running your finger along the thin gradient on the shell, or tap on the silvery triangles lining to change the channel.

The patterns are screen printed in palladium, a rare and fairly recently-discovered white metal that also happens to be a conductor.
