The president of a Japanese electrical manufacturer was interested in seeing the inside of his ear (who knows why), so he made somebody invent it. The result was the Earscope S, launched a few years back without much demand. The product was further developed over the years, and the outcome was the Earscope GXL, a high-end model for household use with a 7400-pixel image. It shows an image of your ear at four times the original size. This thing took off so far that actual earcleaning parlors are opening around Tokyo with Coden Video Earscopes plugged into a monitor with the customer eagerly watching the ear cleaning happen. As for the home model, you can not only check out your internals, but also enter the world of your car engine, computer, fax machine, etc. Prices begin around $172.
