In the world of cell phone design, it seems as though nothing is off-limits...take the Radia cell phone 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 from Mobile Whack, 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?
