I believe its surface plasmons (gold?) being used.
a
Seb - this is difference in that it bends like away from the object, more like water then light. A magnifind glass is a lens, where this is refraction.

And to CapCrunch, yes one of the issues is that the object being cloaked cannot look out either. I believe another issue is it does create a shadow.

(ps: sorry for the sucky spelling)

Yeah, magnifying glasses are based on refraction as well.
All Refraction means is that light will bend when it enters a material where the speed of light is slower than it is in what it just came from.
