This is a stereoscopic render of a planet that I call Delta (a provisional name--I'm sure it'll change later).
To view this properly, you'll need to make sure the whole image fits on your screen. You'll see the planet from two different angles. Cross your eyes until they overlap. Once they come into focus, the planet should pop out and appear three-dimensional.
This can be difficult to do. If it doesn't work the first time, you may have to try some more. Note however that some people can't focus their eyes this way. If you can't do it, stop and give your eyes a rest. Anyway, give them a rest when you're done because they'll need it.
I used to do a lot of these. I, too, found that lots of people cannot cross their eyes! More than I imagined. I used to think that everyone had that ability. Now I do a lot of anaglyphs and make 'em have to use the red/blue 3D glasses...
Looks good, though!
