When I first saw this thing, I thought it would be great to put on children, so that they'd know whenever a creepy man was in the vicinity and notify the authorities. Well, it turns out pedometer is a misnomer, and this thing actually tracks how many steps you take. You rock it on your pants, and then upload the data to your computer and it'll show you calories burned, etc. They cost $17 via usbfever and ship in early November if you're interested. This thing might actually be a pretty nifty workout device, because with that sweet bullseye design you're gonna be doing plenty of running to your car as rooftop snipers take aim.
