Concept – PC Security Ring
Check out this security device concept from designer Yang Hai.

It consists of a base unit and a ring.
The idea is that the ring slips over your finger, which interacts with a base station close to your computer.
When you step a certain distance away from your computer it locks down your PC, step back within range of the base unit and the PC unlocks.
