On all my computers at work and at home I have Giger's "spell" as background image.
I scanned it from the book and retouched the book binding.
Now www.giger.com uses the same picture on the start page, but smaler and not so sharp. But at first I though my old netscape crashed again. Looked like the background image shined through.
I like the band you had playing in that pic more than the wallpaper, Cryptopsy jams.
Since I don't use this PC for anything other than recording, my desktop is plain white (conserve all resources!). My other PC has a scanned pic from an OLD Venom concert flyer.
