Hey, everyone- I did a quick little hack on the Aqua theme for the GTK 
(as well as fooling around with the GIMP for endless hours of fun : ) 
and managed to get something resembling Apple's Aqua for KDE2; take a 
look at http://www.inficad.com/~nytehorse/aqua/index.html and tell me 
what you think.

Of course, you should be running KDE2 if you'd like to be able to really 
get how cool (I think) this theme is. : ) Enjoy!
