Make your own color changing RGB backlit whiteboard: useful in daylight and pretty at night. For extra coziness while working late hours in the lab (video).
I needed a whiteboard and had this spare table top: frosted glass plate with an aluminum frame. While putting it up onto the wall with two strong hooks, I thought it would make a great diffuser for a lamp. Let it be a white board and a source of indirect light in arbitrary colors. And that's the idea of my FnordBoard.
