Orly Shade Shifter Color Changing Gel FX Coat...

Remember this scene from the movie Total Recall where a secretary or receptionist changed the color of her nail polish with the tip of a little stick?

Here on top of the image you can see the "magic" stick.

Ok so it may be a little old for most of you since this movie came out in 1990. Still, it was a pretty neat trick. I personally flipped when I first saw it and even if I wasn't much into nail polish I just loved the idea. Who knows, if it had really existed maybe I would have gotten a little more into it.
