I rather like the way the 'tree' wallpaper scrolls slightly when you move from desktop screen to desktop screen. Unfortunately I'm not that big on trees! Is there a decent way to make your own wallpaper and yet retain the scrolling effect?
Actually, all wallpapers do this. Just take your wallpaper, and it'll automatically zoom in to allow scroll-to...scroll. Make sure it's real high-resolution, though, or you'll really see pixelation because it needs to work for both Vertical and Horizontal viewpoints (hence, a lot of zooming).
