The tiles are layers of glass and colour fused together, with a specially made LED pcb contained at the back, which illuminates the bubbly texture of the glass.
Great! I’ll never again have trouble finding the bathroom at 4 am! The article doesn’t make any comments on how are the tiles powered and the pictures don’t show any type of plug, so I hope it won’t be necessary to knock down the walls in order to change the batteries 😛
Very nice idea, and practical too. The whole designboom site is just as interesting, whether you’re a contemporary industrial design lover or just want to see some cool, -even useful- stuff.
