This is a Photoshop-enhanced screen shot from one of several "Doily" programs I wrote in QuickBASIC. This one moves a kind of kite-tail multi-colored streamer about the screen trailing colors behind it on my monitor screen. It would probably make a nice, if slightly old-fashioned, screen saver (it's low-res, at 480 x 640 in 16 colors; the maximum available in QuickBASIC). I enjoy running it now and then, just to watch. See also the images under the Doilies heading.
