We've been talking about flexible batteries for years now, but a team of Korean researchers have presented a new solution to bendable energy sources that is not only more powerful than standard lithium-ion batteries, but also potentially cheaper to produce than its malleable predecessors -- and unsurprisingly, everyone's favorite wonder material, graphene, is at the heart of the innovation. The rechargeable battery contains a vanadium-oxide cathode, grown on a sheet of graphene paper, an unidentified separator, and an anode made of lithium-coated graphene. According to the folks behind the new power source, it sports higher energy and power density, as well as a better cycle life than the literally stiff competition. Similar advances have also out-performed rigid lithium-ion batteries, but have enlisted carbon nanotubes, a material more expensive to produce than graphene. Of course, like all technological advances, we won't be seeing these things for years, if not decades, so you might as well get used to ye olde standard bearer.

Nintendo Entertainment Systems have proven to be fertile ground for the DIY community -- purses, guitars, and belt buckles are just a sampling of the more unusual NES mods out there. We've also seen our share of NES PCs, and now an enterprising Finn going by the name Ana-5000 has crammed a fully-fledged home theater PC into everybody's favorite 8-bit console. An Asus AT3IONT-I Deluxe motherboard with an Intel Atom 330 dual-core processor and an NVIDIA Ion GPU provides the computing power and offers HDMI and VGA ports, six USB 2.0 ports, optical and RCA audio connections, integrated 802.11b/g/n wireless and Gigabit ethernet, and Bluetooth connectivity. Ana-5000 gave the repurposed Nintendo a fresh black and white paint-job to set it apart from your garden variety NES as well.

In addition the the announcement of the iPad 2, Steve Jobs just unveiled iMovie for iPad, so all your tablet video editing dreams are about to come true. So what does this new version of iMovie have in store for you? A precision editor, multitrack audio recording, some brand new themes, AirPlay to Apple TV, and the ability to share videos in HD. It'll be available on March 11th (the same day as the new iPad) for $4.99. 
We can't say we were expecting to be impressed by a case for the new iPad 2, but Apple's pulled something of a surprise out its hat with its new Smart Covers for the tablet. Available in multiple colors and in your choice of polyurethane or leather variants, the covers attach to the iPad with a self-aligning magnetic hinge and can also be folded into a triangle and used as a stand. What's more, they'll automatically wake or put your iPad to sleep when you open or close the cover, and they even pack a microfiber lining that cleans your screen each time you flip it open. As Steve Jobs explained, Apple designed the covers right alongside the iPad itself and, as he points out, "it's not a case -- it's a cover." Look for the poly covers to set you back $39, while the leather ones will run $69 apiece -- video is after the break.
This collection of devices -- from Germany's SKS Hinkel, and winner of an iF Product Design Award this year -- is really a video intercom system. But if you use your imagination, from left to right, it looks like an iPod shuffle, an iPod classic, an iPhone shuffle, and an iPhone classic all developed in some awesome alternate dimension where coiled phone cords are still cool. 
We've seen WiFi detectors used for various DIY projects before, but none quite like this rather ambitious project cooked up by Norwegian designers Timo Armall, Jorn Knutsen, and Einar Sneve Martinussen. They built a four-meter long WiFi-detecting rod that boasts 80 LED bulbs and carried it around various neighborhoods in Oslo, picking up signals of various strengths from nearby WiFi networks all the way. That's only the half of it, though. The real kicker is that they also captured the whole thing with long-exposure photographs to effectively paint the "invisible terrain" of WiFi networks with light. Head on past the break for a video, and hit up the source links below for a closer look at the entire process. 
Last year, Rensselaer Polytechnic Institute students built a virtual reality contraption that let them soar through the sky, held aloft by a trapeze harness and seeing through HMD-covered eyes. This year, they're controlling it with the power of their minds. For his master's thesis, project leader Yehuda Duenyas added an Emotiv headset -- the same one controlling cars and the occasional game -- to make the wearer seemingly able to levitate themselves into the air by carefully concentrating. Sure, by comparison it's a fairly simple trick, but the effect is nothing short of movie magic. See it after the break.
