This cool device uses 19 tiny LEDs to display the time in thin air! Using the rotation of the blades and well timed LED control, it will display an analogue-style clock with the current time, This is only possible due to a human trait called “persistence of vision”. It’s the same thing that makes “sparkler trails” and other fun things possible. It’s mounted on a gooseneck so you can position the fan/display to your liking, and includes a pushbutton on/off switch. USB-powered from your computer or via a USB mains adaptor.
