One step down from the USB Microscope is the USB Earscope. It’s basically a microscope with a 10x to 50x magnification ratio, an LED light, and software so you can see the inside of your ear on your notebook. The primary purpose seems to be to clean your ears thoroughly.
The earscope is sold by – who else – Thanko and costs 9980 Yen (60.70 Euro).

Wow… I’m speechless.
