Frispeas in the Night
So you thought frisbees were only to be played during sunny summer afternoons?
German designer Petra Tefsger has made Frispea, a frisbee that visualizes its rotational speed. It is white in the day, but it glows blue when night has come and nobody is playing. A light throw makes the frispea turn orange, but throw it faster and it will get red.
