Trippy Persistence of Vision Double Fan

Here is another trippy toy that puts on a dazzling light show as soon as you turn it on. This Persistence of Vision Double Fan has 5 LEDs that flicker at different speeds to give the illusion of streams of light instead of individual dots.

When the device is turned on, it displays lights in red, green, yellow, and blue. You can give the blades an extra spin to further experiment with this toy.
