Michael has built an LED cube that is impressive. Not only because it looks fantastic, but he also managed to process 142 frames per second, that is 1 frame every 7 milliseconds. Within this period, it loops through a still frame 7 times (Each cycle of POV lasts 144 microseconds). This can compensate for flickering during video recording, allowing all cameras to record fluid video without distortion.
A good project to learn about bit-shifting
