I've pretty much used up my mousing hand this evening, downloading pics from the Landscape section of the National Geographic Photo of the Day Archives (wallpaper). These are stunning pics, of course, and made available pre-formatted to fit either 800x600 or 1024x768. I downloaded about sixty of them before my wrist gave out, not to use as wallpaper per se, but as screensaver fodder for OS X's Screen Effects. So now when my Mac is idle, I (or Nola, or the cat) am treated to ever-changed views of the corners of the globe, courtesy of NGS.
Shoo! Go look at the pictures.
