My desktop is boring

Does anyone know of any good web pages to go to and/or programs to use to customize my desktop?? Also i am looking for ways to speed up my powerbook.

Not sure if you mean "mod" your desktop or just replace the wallpaper if it is the latter check out DeviantArt - The Largest Online Art Gallery and Community or The Apple Collection key points you should know (2019) for wallpapers. As for modding your desktop this is a good place to start:
http://www.resexcellence.com/themes/

yea, themes like that at resexcellence will require shapeshifter which changes your macs theme, candybar is also a good app for changing icons like the trash and such. interfacelift.com is also a good place for wallpapers and icons, iconfactory.com is good for some icons, macdesktops.com also has a lot of good wallpapers.

if you want something really snazzy, you could use OSXPlanet

a good way to figure out what you want is to check out what others are doing in the official desktop customization thread.

I am look more for complete mod stuff. I would like to change the icons and the dock, or just make everything really strange.

I think you're looking for shapeshifter (like macman said above):
http://mac.softpedia.com/get/Utilities/ShapeShifter.shtml
It lets you customize background (*not hard) and icon sets and the menu bars and all sorts of wacky stuff...I think the easiest Icon editor alone is candybar (once again a quick macman call):

That's all for me.
