From reading the end of this article, it does not seem to difficult, and I might get on it.

Cool!
When will somebody do a set of car windows?

how about that big car with cameras and LED screens

You would need a lens the size of your car spaced like 2 cars apart on each side to hide each window. Hiding the edges of things with lenses is nothing new, the "novel" approach here is all about using 4 lenses to also correct for parallax (which is pretty cool) Unfortunately it's still a pretty limited use.

Forgot that I started this thread. Anyways, I want to try this out, even if the uses are limited. Would be a cool trick to see through my hand.

Interesting concept, but it only works on-axis. Shift the viewpoint and you lose the effect. In theory you could also build a lens system that hides an object at the centre instead using concave conical (at each end) and convex ring (in the centre, around the object you're hiding) lenses. With both approaches you lose a little brightness.
I prefer an approach using software controlled integral imaging camera / display modules with position / angle sensors to map the incoming colour from a particular position / angle to the directly opposite position / angle.

It'll also work for a few solid angles off axis, depending on the size/placement of the optics used.
I agree, the camera / projector is the way to go, but the farther off that projector line you get the more shift there is between the boundary of the object and what is visible behind it.
