I'm calling bunk on this one.

In this picture they have someone underneath the 'invisibility blanket' which they claim bends light around the person being concealed. How would the invisibility shield know what is beneath the person if the person is laying on the ground?

Not that I'm saying said technology works, but it could be something like this:

Although I would assume the range of cover of the cloak would have to be much larger than shown in the image and it is hit-or-miss in Photoshop when using that feature.

Plus, why would the cloak, if it works as described, cast a shadow?

Edit: Ah, I see now. On the actual site they admit mockups. But why not make the mockups more accurate by reducing the shadow in Photoshop as they claim the cloak only casts 5% of the resulting shadow. But if it casts even that little of a shadow would the cloak not show that on the visible side? Wouldn't the cloak stand out by being slightly darker than the surrounding area?

Well it's obviously a mock up but let's say there's actually a layer under the person as well. So let's say light activates the material on one side which is connected by a smartfiber to an opposite point on the bottom. The color of the surroundings on the bottom are then sent back to the first point via the smartfiber which then emits the color.

An incredibly miniaturized version of the famous Mercedes commercial:

It doesn't sound like anything that's remotely cost effective today so I'd guess it's all hyperbole at this point as other commenters have said.
