DIY "Rings of Death" force field to guard your laptop

When I spied the title "Guard your Laptop with Electric Rings of Death!," well, I had to check it out. And what did I find? Awesome pics of what looks like a bright electric force field circling a laptop! What is this? A DIY electric fence to keep unauthorized sticky fingers off your keyboard? Is it for real? Well, turns out this project is simultaneously very geeky and very cool.

Okay, so it's not a real force field. No, it will not zap your roommate for attempting to access your passwords file. However, creator TeslaDownUnder, says that, yes, the photos are for real and not Photoshopped. It's all done, he says, using a gadget involving rotating electrodes, which was then photographed in a dark room on a long exposure. Voila! Instant force field. Nope, it won't harm a fly. But it looks cool!
