The idea of LED-embedded bathroom tiles has useful written all over it. But unless you’re completely remodeling, they’re going to give you some installation challenges. This Tile + Light concept created by Korean designer Hyomi Kim makes it easier, with snap-together tiles in four different shapes, letting you change the design of the lit-up tile show at your whim.

To hook them up, you just connect one of the tiles to low voltage, and it conducts that current to all the others in its secretive way. Then you can arrange the shapes into whatever pattern amuses you at the time. Could this be part of the bathroom of the future? Looks like a great idea, but Mr. Kim, make it completely waterproof so it’ll work inside a shower or in a pool.
