A new image I made last night was a two quarters image that I altered and it look like an alien face:

What do I use them for? I make these small images to post to my background. If you set the images up just right, you can see them in 3-D on the monitor as a background. Probably nobody uses that feature anymore on the screens, but I have 100,s of images. A lot appear on my images for credit to the one how took the image. If anyone is interested in these, I could create a thread of these images.
