its a non working trick. i dont see depth at all. i do believe it can help for a true 3d screen to make it a bit better.It's already been done. There are some games that draw the screen based on the position of your eyes (seen with the front-facing camera). The only drawback to this is that the 3D doesn't pop out of the screen, but looks more like you're looking deep into the screen and seeing stuff below it.
