The DeskScapes gallery on WinCustomize gets a steady flow of submissions each week. Lots of these are of landscapes and nature, but those also look and work well on the desktop. I wanted to highlight some recent entries as DeskScapes is an awesome way to put some cool animation on your Windows desktop.
