Just having fun in Photoshop recently: took a shot of Monument Valley in Utah (on the Arizona border) and repeated it shrinking the size each time. The first thing I did was select an area of the scene, copy it, then I used the Edit>Tranform>Scale command to shrink it. After that I just used the Edit>Transform>Again command and shrank it a bit more. Very easy and fun to play with. But click the photo to see it full size and the effect is more fun. I'll explain the technique in more detail if anyone is interested.
