I’ve seen magnetic paint and chalkboard paint, but I’ve never seen conductive paint before. Bare Conductive makes conductive paint that allows you to paint electrical circuits anywhere: floor, ceiling, clothing, walls – anywhere but skin. The paint is water-based, non-toxic, and air-dryable. Once dried, it becomes the circuit. You can paint over it so it blends in with the surface it’s painted on, and you can even paint another layer of conductive paint on top without interfering with the previous circuit. Check out the Bare Conductive website for ideas, and go to ThinkGeek to purchase some Bare Paint Conductive Paint for $29.99.
