Don’t buy this "clock" if you want to be able to tell the time – it doesn’t actually do that. No, what this clock does is draw a perfect circle every hour. See the pencil attached to the end of it? Just place the clock against a sheet of paper (or your wall, if you’re feeling devil-may-care enough) and watch as the hand makes its stately progression around the clock face, drawing you a circle as it goes. Why would you need a device to do this for you? That’s for you to decide. You’ll also have to decide whether you need one in yellow, pink, blue or green. Good luck! Product Page | [via OhGizmo!]
