here are some backgrounds that have transperencys so you can choose the background color/gradient.
screenshot #1 is the plain background
screenshot #2 is says "Kdesktop"
the download is a Unitarian Universalist wallpaper (a religon other than christianity!)
please comment weather it be critisisum or just state what you like, i am interested in seeing what people are looking for in a wallpaper
*update i made the left side somewhat trasnperrent, if it is not enough you can change it with the gimp*
