iMpulse is the world's smallest wireless controller for mobile devices
Some KickStarter projects make you sit up and take notice, and the iMpulse certainly fits into that category. It's a key ring that doubles up as a wireless controller for your iOS or Android device.
More than that, it lets you control your media, take photos without touching your phone or tablet, and if you install a special app, it'll even make a sound when you're trying to find your keys.
You can use it either way round, so if you're a wierdo who uses controllers backwars you're well catered for, and you can even sync two to the same device, opening up a whole swarm of multiplayer possibilities.
The device connects through bluetooth, so battery life shouldn't be too much of a problem, and it even has a stylish sliding lid so you don't accidentally smash all the buttons while you're carrying it in your pocket.
If you're interested in throwing down some cash in the general direction of a tiny controller, then head over to the KickStarter page and get donating, you'll be doing us all a favour.
