Spinning LED clock tricks your eyes and tells the time
By rapidly spinning a blade that contains an array of flashing LEDs, this wall clock tells time in a visually striking way. You may think that the watch has thousands of LED’s (8000 to be precise) but instead it only has 33 of them. By spinning a thin LED arm at 30 revolutions per second it tricks your eyes. The clock has several display modes including digital, analog and pendulum, it can also display text messages upto 240 characters long.
