That looks a little like Unicron, man. Savage.
The wallpaper is from deviantart.com. It was made by Niteangel, who is also a member on
www.depthcore.com, which is a site CHOCK FULL of awesome wallapaper material such as the one I'm using.
I demand that we NOT EVER EVER EVER be told what's in those folders in the upper right.
As some people know, I live 50% of my life online. I love downloading all those shitty little 2mb clips of some lady getting her arms chopped off, dogs getting sucked down storm drains, various porn clips which help me find the movie they came from, and even little flash clips or games I find while browsing. Yes, you are correct in assuming that there are some questionable things in those folders, but not everything is bad.
The reason it is in "temp 1, temp 2, temp 3" is that after a few weeks, my desktop is cluttered from the stuff that "made the cut" (read: not deleted) and I just basically select everything on my desktop downloaded, and plunk them in a folder. After a while, I accumulate enough data to fill a CD, and I burn them for archive purposes and start again. This process takes quite a few months. As you can see
from an earlier desktop, there were less folders, because I had less stuff. I don't download as much crap nowadays though because nothing really impresses me that much; very few things "make the cut".
