Looking for a fun stocking stuffer that I’m pretty sure your intended recipient doesn’t already have? Then check out Quantum Bits. They’re little light up thingies that react to motion.
Just toss em around when you’re bored, and the tiny motion sensors inside will cause a pair of bright white LEDs to blink when they move around. In addition to throwing them in the air, you could glue them onto your shoes so they light up with movement, or even attach them to a speaker so they blink with the vibrations. I also like the idea of velcroing them to my cat’s paws.
Each Quantum Bit is rated to last up to 100,000+ flashes, so they should keep blinking for a good long time.
For $19.99(USD), you get a set of eight Quantum Bits – and you can order them over at ThinkGeek now.
