Because soon our backpacks won’t carry anything but video messages, this is a clip from Yihong Technology demonstrating their persistence of vision backpack, that uses a spinning 4-rotor fan with 510 rapidly blinking LEDs to display video. In this case, everyone’s favorite plumber, Mario. WHY he’s everyone’s favorite plumber is beyond me, because I hired him to fix a leaky shower and he took off halfway through the job to “go save the princess.” Some work ethic! Now I have black mold in the basement.

Keep going for the video, as well as a few larger applications of the technology with MULTIPLE fans.
