I've been meaning to offer up some wallpapers, but I kept forgetting. Also, it's hard to know the best screen resolutions to choose, so I'm just hoping these will be suitable for most of you. Let me know if they aren't--I can make more. If you like this idea, I'll make more wallpaper designs to post regularly.
Here are two options for computer wallpaper. Click on the resolution that's closest to yours to open the picture (you can check your screen resolution here, although I've heard it's not always accurate). You can then right-click on top of the image and "Set as desktop background..." or whatever the similar wording is in that menu.
