Doctor Strange definitely needs this NERF blaster – a gun that generates animated spells out of thin air. This truly is wizardry. This cool hack comes from a Japanese cosplayer, and it is able to achieve the effect by using a spinning LED wand.
Do you like to jump rope as part of your exercise routine? Let me introduce you to Tangram Factory’s Smart Rope, a jump rope with 23 LEDs embedded in the middle of the rope that light up in front of you to display your current jump count while you’re jumping, courtesy of the old persistence of vision effect.
Remote-controlled helicopters can be fun to fly, but they’re not exactly easy to see in the dark. But these little R/C choppers not only light up when flying, their blades can display messages while airborne.
I’ve always been a fan of stuff that uses the persistence-of-vision illusion to create images which aren’t actually there, but appear thanks to the trick that our eyes and brains play on us when trying to recreate images from pieces.
Check out this cool clock made from an old hard drive. Built by modder Svofski, the clock tells time on the face of the hard drive’s rapidly spinning platter.
The Strobeshnik hard drive clock uses a stroboscopic effect to make it look like the numbers of the clock are persistent on the face of the drive platter – which Svofski galvanically etched to make the cool cutout numbers.
This flying saucer-like apparatus from Bandai is a modern day take on a classic kids’ toy – the spinning top.
Just flip open the collapsing handle on the Bandai Luminodisc and give it a spin. As it goes round and round, a persistence-of-vision LED display tells you how many rotations your spin made.
Weird gadget time! This USB-powered fan has LEDs on its blades that can display colorful patterns or one of more than 30 preset text messages. Why more than 30? I don’t know. What’s it called? The “USB 30+ Light Show Fan.”
