Going around the bend! - 3Dfication.

Here's another one of those image manipulation programs. This one is by Niels Noordhoek.
This is an image of the full Moon that I took last year.

3D Moon, red & blue glasses needed.

NB. I always find the best thing to do is to move closer to the image whilst viewing, then the 3D pops into your head.
