Invisibility Cloak - The Future is Clear

It is 2011 so...

Where is my flying car and house on the moon?
Where is the robot to tidy up my room?
Why hasn't the common cold been cured yet?
And why after all these year do we still have a National Debt?

At least the future we dreamed of is here in some areas even if the areas of advancement seem more unlikely than those mentioned above.

According to my friend Graham the Klingons and the Romulans have had cloaking devices for eons and now thanks to Fractal Antenna System Inc. Earthmen are catching up. The video is proof of concept of an invisibility cloak all be it one that only works at microwaves. Bearing in mind the military implications one wonders what they are not telling us. The potential for Fractal Antennas is huge, a lot of this is due to the almost infinite number of resonant electrical lengths within a fairly short length of the Fractal Metamaterial. This may seem hard to understand for anyone not familiar with the work of the mathematician Benoit B. Mandelbrot, but fractals are regarded as the geometry of nature. A fractal is described as a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole.
