Those aspiring to become high-tech spies can look into this nifty gadget by Taiwanese manufacturer Misumi. Dubbed as the "snake camera", this small 4.4 mm diameter camera is claimed to be the world's smallest camera ever.

The snake camera is only 15 mm in length, with a snake bracelet attached at the end so users can just wrap it around their wrists. It comes in a 320x240 resolution, however, but that can be considered a just pay-off for its remarkable smallness.

Misumi's official website has more than 10 variants of the snake camera, so you can pick and choose according to your tactical espionage needs. Some even feature Sony image sensors and LED lights for optimal image capture.

The possibilities are endless: you can easily conceal the camera underneath your sleeve (with the lens peeping out, of course). Or you can slip it underneath the door of the room that you want to spy on.
