In the world of cell phone design, it seems as though nothing is off-limits...take the Radia cell phone [0] for example. Well here's another concept phone to add to the collection. Designed for NEC by US designer Shaik Ridzwan, this phone has been created to look and feel like a real yoyo. Featured on Trend Hunter [1] from Mobile Whack [2], the Yoyo phone lets you wrap your headphone strings around the base like an actual yoyo string. It also comes with a flip-top clamshell style lid to keep the keypad protected. I like the colors, but I need to know more before getting overly excited. What do you think? Love it or leave it?
