When Logitech and Microsoft released a bunch of HD webcams last year, Skype refused to certify them for use with its HD video calling service. (That's not to say these webcams won't work with Skype HD -- it's that Skype won't guarantee that they'll work well.) And why this resounding slap in the face? Because Skype will only certify HD webcams that come with onboard video processing and therefore run even on tardy old machines. And that is precisely why Creative has followed the lead of other manufacturers likeFaceVsion and Freetalk in including a built-in H.264 encoder with its latest offering, maintaining judder-free video and a chill-axed CPU. The webcam also has more flexible autofocus and a "quad mic" system, which together should allow users to sit as far as 10 feet away and still be seen and heard clearly. The only problem? A $150 price tag that's significantly more than the competition and only slightly easier to face than your cousin's ac...

There are a few robots smart enough to solve a Rubik's Cube in seconds flat, but a group of students at Swinburne University of Technology think theirs may be the fastest on Earth. Their bot, named Ruby, recently mastered the puzzle in just 10.69 seconds, including the time spent analyzing the cube. To achieve this feat, the device scanned the toy with a webcam before its software processed the images to crank out a solution. According to the university, Ruby's 10-second mark smashes the current world robot record of 18.2 seconds, unofficially making it the fastest cube-solving machine on the planet. But Ruby still has a long way to go before it catches Feliks Zemdegs -- a 16-year-old Australian who solved a Rubik's Cube in 6.24 seconds and continues to carry the torch for all of humanity. Twist and turn your way past the break for the full PR and a video of Ruby in action, as well as a clip of Zemdegs showing us how the pros do it.

Practical or not, there is no denying the nerd-gasm inducing wow factor of Microsoft's Surface. Of course, Surface is expensive -- like, unless you're a millionaire you're probably not buying one for personal use expensive. There are some DIY solutions out there, but designer and developer Seth Sandler has come up with the cheapest and easiest yet. Built from about $400 worth of material (some of which you probably have lying about your home / apartment / dungeon), the MTbiggie brings big-screen multitouch to the masses. Like the hacker's previous homebrew multitouch device, the MTmini, there's nothing particularly difficult to find here. All you need is a couple of chairs, a mirror, a projector, an infrared webcam (which you can easily hack together with some old film negatives and cardboard), a big sheet of paper and an equally large piece of clear acrylic. Just set it all up according to the instructions in the video below and in no time you be fing...
