The LIFX is a really cool Kickstarter project that basically is a WiFi-enabled light bulb that will let you change it’s color or dim it using your iPhone or Android phone. They are quite expensive but the inventor says they will last up to 25 years. Check it out:

This is a pretty unique gadget. It’s a pair of gloves that works just like if you had a real piano to play with. Just put on the gloves and use any surface as it was a piano. Each finger tip represents a note and the device features 8 different instrument sounds, 8 background rhythms, and 6 built-in demo songs. Pretty neat and the price is $35.
