trompe l'oeil (tromp lye) noun

1. A style of painting in which objects are rendered in extremely realistic detail, giving an illusion of reality.

Examples of trompe l'oeil [per Anu]: http://trompe-l-oeil-art.com/

A "trompe l'oeil" is a 'trick of the eye' which only works if you discover you've been tricked.

Gotcha!

That's what makes it different from other fakes. You're supposed to discover it's a fake. That's what makes "faux" fun.

Now you see it. Now you don't. Get it?
