Digital tests on fridge

People need to eat frequently, and the refrigerator is a common place in the household where people go a lot. With this in mind, it was a common place, in the paper age, to hang pictures, to-do notes, and high-scoring tests returned by teachers. I feel like this tradition could be dying, and I think it's important to give children this sort of spotlight to encourage further achievement. Proposed is a fairly rugged digital photo frame with strong magnets designed to be placed on refrigerators in households with children. Unlike prior art, this photo frame would be specifically optimized for letter-sized documents (8.5"x11" in the US). It would feature a wide viewing angle to be plainly visible at all heights. In one embodiment of the idea, it may even be powered by the refrigerator itself to avoid battery consumption and the hazards of wires (e.g. choking, tripping, etc.).
