How is this possible?

I remember reading about something like this, it had to do with bending light around an object and then connecting it around a point at the end. This would make an invisibility effect. Though, last time I remember hearing about this, I think scientist were only able to produce an object that can do this the size of a hair follicle or something. Dunno if they managed to make it bigger.


Edit - Oh, someone already posted about that. I remembered more about how this works than I thought. I think I wrote up my thoughts about this too somewhere, too lazy to check in my computer for it.
