Okay, so we're not up to USS Pegasus levels yet, but for the first time researchers have been able to cloak a three dimensional object. Don't start planning your first trip to the Hogwarts library restricted section just yet though, the breakthrough is only in the microwave region of the EM spectrum. Using a shell of plasmonic materials, it's possible to create a "photo negative" of the object being cloaked in order to make it disappear. The technique is different to the use of metamaterials, which try to bounce light around the object. Instead, plasmonics try to deceive the light as to what's actually there at the time -- but because it has to be tailored to create a "negative image" of the object you're hiding, it's not as flexible, but it could be an important step on the road to that bank heist we've been planning.

He was appointed with a fair bit of fanfare as the United States' first Chief Technology Officer back in May of 2009, but it looks like Aneesh Chopra has decided that it's now time to make room for the nation's second CTO. The White House confirmed today that Chopra is stepping down from his position, noting that he has amassed a "dizzying array of accomplishments." Among those are his contributions to the Obama administration's national wireless strategy, a set of internet policy making principals, and a number of efforts related to the President's open government strategy, including the Data.gov platform. No word on his successor just yet, nor is there any official word on what Chopra plans to do next -- although The Washington Post reports that he's expected to run for lieutenant governor of Virginia.

There's something romantic about hacking the iPhone, especially when it means finding ways to personalize the massively popular handset. Apps like Instagram may help you realize artistic talent, but software just doesn't get those creative juices flowing like an old-fashioned piece of hardware can. Despite its taboo-sounding name, The Love Box isn't an adult toy in the traditional sense, instead serving as an analog video (and stills) mixer for your iPhone 4 or 4S. Consisting of a wooden box and an angled sliding mirror, the homegrown contraption lets you simultaneously capture the action in front of and behind you in a single image. It was originally designed in Barcelona to capture two people conversing for a documentary called "The Love Box Conversations," hence the name. The "lowest-tech accessory for the highest-tech phone" is available now as part of a very limited initial run of 100 units, and can be yours for €57.63 (about $77.50) if you hit up the source link below.

It's no secret that certain countries have different views over freedom of expression on the internet, but this hasn't stopped Twitter's attempt to keep its service running in as many places as possible. In its latest blog post, the microblogging service announced that it'll begin "to reactively withhold content from users in a specific country" when required, in order to keep said content available to all users elsewhere (as opposed to blocking it globally). The withheld tweets will be marked accordingly while their authors get notified with reasons where possible, and internet legal rights monitor Chilling Effects will also post the relevant take-down notices on a dedicated page.

This may seem like some form of censorship taking over Twitter, but the company only mentioned those of "historical or cultural reasons" like the ban of pro-Nazi content in France and Germany; so it's not clear whether Twitter will also handle similarly with tweets that potentially lead to events such as the UK riots last year. Even though Twitter didn't elaborate further for Reuters, there is one reassuring line in the post:

"Some [countries] differ so much from our ideas that we will not be able to exist there."

One such country is most likely China, and back at AsiaD in October, Twitter CEO Jack Dorsey told us that there's simply no way for his company to work with the Chinese government (you can watch him answering us at 38:17 in the video -- courtesy of All Things D -- after the break):

"The unfortunate fact is we're just not allowed to compete in this market, and that's not up to us to change. The person to ask is trade experts between both governments, but at the end of the day we can't compete. They (Chinese microblogging platforms) can compete in our markets, and we're certainly interested in what that means for us... We would love to have a strong Twitter in China, but we'd need to be allowed to do that."

There are obviously many factors that add up to this sour relationship, but the contradiction between China's strict internet monitoring policy and Twitter's core values is most likely the biggest obstacle. And of course, the Chinese government would favor its home-grown tech properties, anyway. That said, several months ago, one of the country's largest microblogging services Sina Weibo was criticized by the authorities for not censoring fast enough, so it's obvious that it'd be even trickier to work with a foreign company that sees things differently. Things are unlikely to change any time soon, or ever, unless China relaxes its policy.

All those long, long drives to Florida in the family station wagon seemed worth it at the time, but now that we've found out that those lucky South Koreans have another crazy theme-park, we might just change our minds. Located near Seoul, Live Park uses 3D video, holograms and augmented reality, interacting with RFID wrist bands and Kinect sensors to stitch together a continuous immersive story. You (and your avatar!) have 65 attractions, over seven themed zones, and the world's biggest interactive 360 degree stereoscopic theater to wave, jump and shout your way through. Two years and $13 million in the making, Live Park's creator d'strict is now looking to license the concept out internationally, with locations in China and Singapore already earmarked. We're not sure we could handle that long of a family drive just yet, but with a Hollywood entertainment "powerhouse" reportedly nibbling, maybe we won't have to.

No, it's not another Fast & Furious sequel, it's something much quicker -- 800 billion times quicker, to be precise. Scientists at DESY (Germany's largest particle physics center) are premiering the Guinness World Record-holding fastest "movie" to a select audience at its light sources users' meeting. The film was shot using an X-ray Laser, and splitting the light in two. By firing one beam off on a minuscule detour (0.015 millimeters) and delaying its arrival by 50 femtoseconds, two separate images are captured. Okay, so two frames isn't exactly Lord of the Rings, but it's still the smallest interval ever recorded. This technique won't be popping up in Hollywood any time soon -- instead, it's actually used for snapping subatomic glimpses of ultra-fast molecular processes and chemical reactions. Despite the brevity of this record-breaking flick, the plot is apparently still more complex than Tokyo Drift.

There are plenty of off-the-shelf controllers out there, but what if you fancy something a little more... you? How about fully customized, with a good seasoning of affordability and style? Design student Alex S has built a framework to help you build just that. The units shown above are for DJ-based programs, but you can create interfaces for any software that takes HID or MIDI input, and as they're modular, create endless ultra-custom set-ups. Keen to dismantle any technical barriers, Alex created a step-by-step Instructable, but you'll still need to get your hands dirty with Arduino and some circuitry. The whole project is open source, and while it's a step up from Lego, until we can just print these things, it seems like a great option to us.

AT&T has released some real gems from its videos archives over the past year, but it's truly outdone itself this week. It's dug up a rarely-seen short film titled Robot that Jim Henson made for Bell in 1963, which was intended to explain computers and data communications to business owners at "elite seminars." It does so with phrases like "Correction: the machine does not have a soul. It has no bothersome emotions. While mere mortals wallow in a sea of emotionalism, the machine is busy digesting vast oceans of information in a single, all-encompassing gulp." Enjoy.

Who knows why tech tinkerers do what they do. We're just happy to see those idle hands try the untested. Like this latest Arduino hack from modder Michael of Nootropic Design, who's seen fit to rig a 16 x 32 LED matrix up to an Android phone for use as a secondary display. The outputted video, downscaled via OpenCV software to an appropriate resolution and 12-bit color, is admittedly unimpressive, as it chugs along at a paltry four frames per second. But that's not the point of this can-do experiment -- it's all about the possibilities, however blurry and pointless they may be (although, we're sure Barbara Walters would beg to differ). Ready to see this modjob in motion? Then head on past the break for a brief video demo.

The block-building stylings of Minecraft bears more than a passing resemblance that timesucking hobby from our childhood. Now Lego and Minecraft look set to symbolize their love of all things block-based in a forthcoming set. The idea was suggested through fan submission site, Lego Cuusoo, which offers the chance for new user-submitted building sets -- provided there's enough interest -- to reach retail. The Minecraft project is the latest to make it through, claiming over 10,000 supporters and managing to pass through the toy-maker's requirements. Lego is now readying a concept that "celebrates the best aspects of building with the Lego system and in Minecraft." We've been promised more details soon -- until then, we're getting back to the digitial mining.

Using Microsoft hardware to augment Android? Surely, you can't be serious? Well, confounding as this may be, it is indeed true... and don't call us Shirley. All fanboy-ism and Airplane! references aside, this Kinect hack (yes, another one) manages to move Ice Cream Sandwich out of its 4.65-inch confines and onto the big screen wall. The inventive and involved mod, borne from hacker Recursive Penguin's desire to demo in-development apps at business meetings, allows for gestures made on a projected interface to be deciphered by MS' famous add-on, resulting in real-time responses. While this particular pico-friendly bit looks simple (not to mention fun to use), it's actually a bit daunting: AOSP ROMs, TUIO protocol and multi-touch software, anyone? While there are, undoubtedly, some of you that could pull off such techie gee whizzery, we'll just sit and wait for Google to implement this in version 5.0. Check out the brief video after the break.

We're still in the relatively early stages of the 3D printer revolution, and as such, it's hard to say just how these devices will play a role in our daily lives. We've seen some really cool toys like turtleshell racers and Weighted Companion Cubes, but what about some everyday products? This 3D printed record keeps the Portal printer theme going by cutting our old pal Jonathan Coulton's "Still Alive" into its grooves. The single was printed over at Shapeways and played on a Fisher-Price record player. Video after jump.
