Forget Kinect — if you're looking for a way to control your computer via natural movements, look no farther than the Leap Motion Control Device. Based on proprietary technology, this sleek, compact motion sensor sits on your desk in front of your monitor, creating a 3D interaction space of 8 cubic feet that is 200X more accurate than anything else on the market — the difference between waving your arm and signing PDFs in the air with an actual pencil.
Sure, it can be useful to check the weather on your smartphone, computer, or local news station, but it doesn't really help you to know what it's actually going to feel like outside. The Cryoscope ($300 and up) does. This crazy contraption heats or cools its top slab to a certain temperature, depending on the mode — time shift mode will give you the forecasted temperature, while space shift can give you the current temperature of anywhere you specify — letting you literally feel the temperature you're looking for. Useful for commuters, travelers, or those who want to torture themselves by checking the current temp in Wailea.
Yes, it looks a little like a science fair project, but make no mistake: the Noise Hero ($90) is no toy. This 4093-based electronic noise maker uses three oscillators, five knobs, eight switches, and one push button to output everything from light, Mario-esque beeps and bloops to grinding, NIN-style growls. As for the low-rent looks? They just add to the charm.
