Love playing pranks on other folks? The iBum Chair sounds like the perfect device for you, thanks to the brilliant Tomomi Sayuda who came up with the idea of a comfortable looking seat which is able to photocopy the rear end of whoever sits on it automatically. There is a scanner right atop the chair that will scan anyone’s buttocks, printing it out on the right hand side of the chair later. A built-in sensor is able to detect the presence of a human in the chair, and more often than not, it will catch virtually anyone off guard. Definitely one of the pointless devices we’d love to have…
