I used to make a big deal out of having the most splendiferous desktop backgrounds on my computers. After all, nothing screams, “I HAVE AN EXCESS OF COMPUTING POWER!” like redecorating your desktop such that it resembles a schoolgirl’s notebook.
My computers don’t have any specific religious affiliation, unlike their owner/operator…
That said, I think that the source of the amazing backgrounds I would use was lost in a horrible “Forgot-to-bookmark-it-and-lost-the-URL” incident, and I found myself wondering (this weekend) — Where did I used to to get those fabulous backdrops?
The answer? Mandolux. 
Some of my recent favorites? Try Bio-Bear, Adrenochrome v2, Three, and Vasectomy.
Oh, and let’s not forget the one in the picture above… Buddha.
