zzContour Screensaver smoothly makes isolines from a timed trigonometrical surface that will steadily scroll on your monitor(s).
There are several options for contours, patterns, and colors allowing you to change up the appearance of the ever-scrolling graphic. It reminded us of an old battle map from some long-forgotten board game.
Because some people have asked about the author both here and on other websites, Javier is a regular visitor and indie developer who creates screensavers and small apps and makes them available to you on MajorGeeks. You may not have heard of Javier before, but MajorGeeks has always supported the smallest of developers since 2001. As always, all files on MajorGeeks are scanned, tested, and reviewed.
