While waiting for my system to rebuild a few apps, I decided to tweak the Internet Map with Gimp…

here are the results…

I opened up the internet map in gimp, resized it to 1600×1200 (so it’ll fit my resolution as a wallpaper), then starting playing with the filters and scripts from the pulldown menu.
Occasionally, you’ll have multiple layers created from script-fu items. Just merge them down.

If you loose all your color at any given moment, you can always hit the undo button.

Here’s a shot of my current desktop.
