Great site with all kinds of eco-friendly ideas, like a solar-powered water filter that you can put into your local pond that will tell you how clean the water is by color, and a keychain gadget that vibrates when you blow this whistle that it comes with. You’d never lose your keys again!
Most of the designs on here are just ideas/ prototypes, many are yet to come out but, still.
Ive come across a lot of sites like this from stumbleupon. But theres some really cool stuff on there. I really like the spiral pen, simple and effective. The brass knuckle mug and salt and pepper grenades are pretty awesome too.
