I'd go back every now and then to see if it was working but nothing. Eventually I deleted the sidebar link but I never really forgot about the site. I Googled it again recently and found that I wasn't the only person that missed that place. It's back up again but only to give links to torrent downloads. I downloaded the full set immediately. Check them out in the screenshow below. I'm only hosting a small version. If you want to get any other size you can find the download links here.
Another one of my favorite wallpaper sites it Interfacelift. I'm subscribed to their feed so I get any new submissions in my reader.
For those of you that play poker on Full Tilt and Poker Stars, these make awesome table backgrounds. The 800x600 size is perfect. If that's not available just shrink down the 1600x1200. All you have to do is replace the Table.jpg file under Program Files/Full Tilt Poker/Graphics/Theme Name or Racetrack/Theme Name. My current favorite is from Interfacelift.
