I played with some colors and some cool large XRay photos I stumbled across. Something about looking at your own human bones really puts you in your place. Looking at objects that make us who we are but are rarely observed, bones and muscles that we just expect to work but don't really question how they do. Makes you wonder how well you really do know yourself.
These are all Large Wallpapers (1920 x 1200) I just put them on my computer and they look pretty awesome I set it to randomly change photos every minute.
