So you want to lock up your computer and just can't get enough of gaudy, wearable gadgets? Then Thanko's got you covered (remember, they hooked us up before with the USB pen/SD reader). Their new USB PC Lock does what you expect—locks your PC—but the real height of geekery is the accompaning receiver (that you're apparently supposed to wear on your shirt, yeah right). When activated, the computer will automatically lock up when you move more than two meters away from it (that's 6.5-feet in American). Thankfully, it'll also work if you put it in your pocket, which we recommend you do. Like, really recommend.
