I started playing around with a little 3D anaglyphic images today. All you need to view them is a pair of red/blue 3D glasses. The process is actually pretty simple. All you need are two photos of your subject matter separated by the distance between your eyes (two image taken with camera slid to the left or right).
Check out more 3D images of my shop here.
