Ring Planet Rendezvous

I've been interested in 3D stereo pair images for a long time, so I thought I'd try drawing one tonight. I started with the main picture, keeping every element in its own layer. Then all I had to do was take a copy of the original and shift the layers right or left to give the illusion of depth. To view it, all you need to do is cross your eyes until the two images merge into one in the middle. It takes some practice at first - good luck!
