This miniaturize effect is a pretty cool yet super simple effect.
This how-to was initially only for Photoshop. But I've updated the
page (it's a wiki) to include GIMP verbage.
The steps are pretty much 1 to 1 w/the GIMP. But what they call
"Reflected Gradient" is actually called "Bi-Linear" in
GIMP (silly Adobe).
Here's what I got (darn near what they got). I also upped the saturation +15.
