My favorite alternative use of peroxide is as a pesticide. Sometimes rather annoying types of bugs get a dose of it, like spider mites who survived the tropical-climate-in-a-plastic-bag treatment.
I wouldn't recommend using it on LCD displays, though, as it might dissolve the surface. Besides, you don't want it to get in touch with acetone (and you never know which materials they used in making that plastic coating...).
If your monitor is a CRT, on the other hand, you're fine. Peroxide is too weak to harm glass.
@Mo: there are three different 'hair zones' in people - 1: head hair, 2: eyebrow, axillary and pubic hair, 3: body hair. As opposed to popular belief, the colors of these zones don't have to match, which means that a person with dark pubic hair may just as well be a natural blonde... heh. It just means that looking at somebody's eyebrows will give you a good idea of the color of this somebody's pubic hair.
