How That Impossible Escher Waterfall May Have Been Built [Video]

Remember this? Still pretty crazy! But maybe a little less so after taking a look at David Goldman's theory of how exactly this contraption was put together:

It's amazing what a little forced perspective and careful editing can do. Remember, though, that this is pure speculation. There's still a distinct possibility that the real answer is magic. [BoingBoing]

HTC Incredible S auto-rotating buttons explained? (video)

We were quite bedazzled by the HTC Incredible S after our hands-on at MWC, but it's the auto-rotating icons for the capacitive buttons that left us most intrigued. So we went back to the HTC booth to try to make sense of it all. From what we were able to observe, there's some optical trickery happening here: the icons appear to be glittering and shimmering depending on viewing angle as if lit through a prism, half-mirror or grate of some kind. We think that a pair of LEDs are used to project the intended icon onto the glass surface via either a combination of prisms and half-mirrors, or via horizontally and vertically polarized grates. Watch our video after the break, and let us know in the comments how you think this actually works.

Dell Rosemount tablet will have Intel's Oak Trail inside, stylus, removable battery and remote wipe

Dell means business with its upcoming Windows 7 slate, if the whispers we're hearing are true -- we have it on good authority that the recently-leaked Rosemount will be a Latitude. An inside source says that the 10-inch tablet will not only sport Dell's storied business brand but will be geared towards enterprise through and through, with features like serviceable components (including a removable battery), software encryption and the ability to perform a remote wipe, and that it'll have a dual-digitizer to support both touch input and a stylus for fine details. We don't know about performance or battery life quite yet, but the slate will reportedly use an Atom chip, specifically Intel's Oak Trail, so we'll let you imagine the possibilities.

The Met's upcoming opera to boast glasses-free 3D effects that nobody requested

We don't mean to sound negative or anything, and we're not 3D naysayers by any means. But the news that the Metropolitan Opera's upcoming production of Siegfried will include mind-blowing 3D background effects is, well, mind-blowing. While you're undoubtedly familiar with 3D effects, you may not be acquainted with Wagner's 1876 opera which portrays the story of Sigurd, a hero of Norse mythology. Robert Lepage, the director of the operation, expects theater-goers to find themselves engulfed in a three-dimensional world of his creation, which will be projected on the 45-ton set. Lepage, who is directing Wagner's entire Ring cycle at the Met, worked with Geodezik -- famous for the stage shows of famed opera performers Pink and Justin Timberlake -- to create the show's effects. The 3D you'll be seeing if you hit the theater won't be like the technology you're familiar with, however, as it makes use of fractals, and the moving parts of the set to 'trick' your eyes into seeing in three dimensions. We don't want to say this sounds like a bad idea until we've seen if of course, but we've got our reservations. Hit up the New York Times link to see one rather small image of the set.

Imagination Technologies unveils Series 6 PowerVR GPUs -- promises desktop caliber graphics in mobile devices (update)

Source: http://www.engadget.com/2011/02/18/imagination-technologies-unveils-series-6-powervr-gpus-promis/

Imagination Technologies may not be a household name, but they created the PowerVR GPUs that are the gold standard in mobile graphics, and are a part of the ARM SoCs you find in mobile devices like the iPhone 4, Galaxy S, and the Droid 2. Not one to rest on its laurels, the company unveiled its new Series 6 PowerVR chips -- affectionately known as "Rogue" -- that are 20 to 100 times more powerful than its previous handheld offerings. That's right, these GPUs will have the same horsepower as today's desktop computers while needing only a milliwatt of juice to deliver face-melting graphics -- the catch is that this bit of black magic won't be showing up in devices for a few years. Guess we'll just have to settle for the Series 5 chips -- like the quad core beast found in the Sony NGP and the upcoming OMAP 5 platform -- which the company promises will make their way into select smartphones "within three months." Be still, our gaming hearts.

Update: Three months? Hardly, ST-Ericsson has announced a series of new SoC processors, including the Nova 9600 that has "Rogue" baked in. The chip delivers HD video at 120 frames per second and can pull off pro-quality 3D video recording as well. Press release is after the break.
