Combining art and maths, much like the Mobius Strip bagel, these mirrored Invisible Shoes reflect the ground, causing small animals to headbutt your ankles. Imagine kicking Lady Gaga in them. [CNET Asia]

And you thought turning your "terrorism 4 eva" tattoo into "terrariums 4 eva" would stop you getting caught. Scientists are working on a new infrared camera that can detect adapted tattoos, which will help recognize crafty criminals.

Supposedly if the tattoo has changed, either by laser removal, adding more ink or even surgery, the infrared cameras can pick up on the change, and actually illustrate what the original design once looked like. It'd prove invaluable for detectives seeking criminals who may've tried disguising themselves, though reports of cameras detecting wigs and fake mustaches are still sadly unfounded. [TechRadar]

That HTC Legend handset from the leaked roadmap we saw the other week has just been given another airing in public, with the Hero-esque aesthetics and specs revealed. LED flash, anyone?

Part of the "Lifestyle" range of phones HTC is cooking up, the Legend will contain a Qualcomm MSM7227 processor, which was revealed earlier this year for budget (sub-$150) smartphones. It'll be fast, but it's no Snapdragon, with the CPU clocking in at 600MHz. Internal memory is listed at 512MB with 256MB RAM, and the battery is a 1300 mAh floozy—again, nothing special, with the Hero having a 1500 mAh battery.

A 3.2-inch HVGA AMOLED capacitive touchscreen, 5.0-megapixel camera with autofocus and LED flash (a one-up on the Hero, there), microSD slot, Bluetooth 2.1, GPS, G-sensor, digital compass, 3.5mm headphone jack and microUSB port round the Legend off nicely, but it's only the addition of an optical trackpad and LED flash which are the main differences between this and the Hero. Supposedly it'll launch in March according to Ai.rs, and the leaked roadmap of launches. I've still got one more question for HTC—will the bottom of the chin actually be red or green? [Ai.rs]

At a mere 7 millimeters in height, Seagate's Momentus Thin drive will be the slimmest 2.5" hard drive on the market. Not only that, but supposedly it will also be one of the lowest-priced storage options for ultra-portables and netbooks.

We don't have details as to exactly how much these drives will cost or when we'll be seeing them in our computers, but we do know that they're shipping to Seagate's OEM and integrator partners at the very beginning of 2010. If the Momentus Thin lives up to all its claims, then its 160GB and 250GB capacities should be a rather attractive option for netbooks. Definitely something to keep an eye on next year.

SEAGATE UNVEILS WORLD'S THINNEST 2.5-INCH HARD DRIVE FOR SLIM LAPTOP COMPUTERS

SCOTTS VALLEY, Calif. - December 14, 2009 - Seagate Technology (NASDAQ:STX) today announced the Momentus® Thin drive, the world's thinnest 2.5-inch hard disk drive for ultra-portable and entry-level laptops, high-end netbooks, backup devices and consumer electronics. At a wafer-thin 7mm in height – 25 percent slimmer than traditional 9.5mm 2.5-inch laptop hard drives – the Momentus Thin drive gives original equipment manufacturers (OEM) and system integrators significantly lower cost-per-gigabyte storage than solid state and 1.8-inch drives, enabling a new breed of entry-level thin laptops.

Of all netbook computers available today, 90 percent feature 9.5mm 2.5-inch laptop drives because solid state and 1.8-inch hard drives are largely cost-prohibitive for this market. The Momentus Thin drive provides the lowest-cost storage for netbooks and thin laptops, enabling computer makers to offer systems that reach a broader market.

"The Momentus® Thin drive promises to help computer makers differentiate on mobile-computing form factor and better compete in the fast-growing markets for thin laptop PCs and netbooks," said Dave Mosley, executive vice president of Sales, Marketing and Product Line Management at Seagate. "Seagate is committed to helping its OEM and system integrator partners meet market demand for thinner laptop PCs and plans to expand storage capabilities for thin laptops as demand for these slimmer models continues to grow."

The Momentus Thin drive rivals traditional 2.5-inch laptop drives in performance and power-efficiency, enabling thin-chassis designs in all segments of notebook computing and allowing OEMs both to design in greater value on high-end netbooks for easier upselling and to create a wider value differentiation between consumer and commercial laptop PCs. The Momentus Thin drive features two capacity points – 250GB and 160GB – an 8MB cache, a Serial ATA 3Gb/second interface and a 5400RPM spin speed. The drive is scheduled to ship to Seagate's OEM and integrator partners in January 2010.

The Seagate® Momentus® family now helps laptop makers give home and business users a sweeping upgrade path – from netbooks, often purchased as introductory, low-cost laptop PCs strictly for emailing and Internet surfing, to notebooks offering mainstream business and consumer applications, to feature-rich, high-performance laptops, all in standard-size and the increasingly popular thin models. Seagate Momentus 5400RPM and 7200RPM hard drives in the traditional 9.5mm height combine the industry's broadest feature set – including self-encryption, FIPS 140-2 certification and free-fall sensors – with up to 640GB of capacity, fast 3Gb/second Serial ATA interface speeds, cache sizes as large as 16MB, and among the highest hard drive shock-tolerance, acoustics and reliability specifications for entry-level, mainstream and high-performance laptops.
