So I've got into cubing recently, and I've got a few different cubes now. One of them is a transparent sticker-less cube. Each tile is made of a transparent, colored plastic and a very simple and cool mod for it could be to have a few LED's attached to the core to light it up from the inside. All attempts at a glow in the dark cube so far have used paint or stickers and are a bit of a let down. Although it sounds quite simple, there could be some challenge in fitting all the circuitry including a suitable battery inside the core. Also it would be preferable to be able turn it on from the outside somehow. It would be really cool to solve one of these in the dark, with all the colors flying around like a mini disco ball or something.
