I've seen a few videos of this in action. They've also applied the cloaking onto other things such as Balls and cubes. It seems to work pretty well, but there are few things that could still use work. As far as I know, special lighting is needed... anyhows, its a crazy concept, but I'm sure that our governments have developed something similar years before this.
Every time I seen young Pete Stein, he brings me beer from Pioneer market down the block from him in Manhatten. Everytime I visit him, we go there and I marvel at the bizarre beer they have on sale. It's basically a Big Lots Of Booze.
