Yes, we know the new Retina MacBook Pro has asymmetrical fan blades to cut down on noise — but ideally, those fans wouldn't be kicking on at all. That's where the AirSlab ($50) comes in. Crafted in the US from full grain Walnut veneer or Baltic Birch, each one is made to fit Apple's 13- or 15-inch portables, and sports a bevy of perfect circular holes to promote cooling, as well as cork feet to attach for desk use — which also means that it's great for keeping the heat away from the boys when your using it on your lap.
For anyone who's ever wanted to make a banana piano, or a kitty-powered photo booth, or any other sort of strange invention, hope has arrived. The MaKey MaKey ($35 and up) is a new, simple invention kit that makes it easy to make whatever you want. It connects to your computer via USB and uses alligator clips to make a connection to pretty much any conductive object you can think of — paint cans, fruit, or even other people — letting you control websites, apps, or custom programs. In addition, the MaKey MaKey runs on top of Arduino, so when you're ready to step up to more advanced builds it'll be up to the challenge.
Scuba diving isn't exactly easy, and it's even harder if you're trying to shoot any sort of decent photos or video. So why not let the HydroView ($4,000) do it for you? This underwater vehicle shoots 1080p video and high-quality stills, which it beams back wirelessly to the same iPad that you use to control it via the accelerometer and touchscreen. Other features include on-board LED lights, the ability to reach speeds of five knots going forward and one knot in reverse, and the ability to collect data on water conditions. Just think of it as your very own remote-controlled miniature James Cameron. [Scouted by Chris]
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.
