Yes, scientists have brought Harry Potter's invisible cloak to life. It works well too as you can see from the picture on the left - the center is now gone and nowhere to be seen. There are just a few niggling problems if you're a Harry Potter wannabe.
First, you have to be no larger than 10 micrometers. That's 100 times smaller than a millimeter. Next, unless you exist in only two dimensions, everyone can see you. This is basically impossible since you're not that circle over there.
Guess you'll have to wait for scientists to come out with a shrinking potion to try this one out.
