This screensaver is written for Windows. It uses OpenGL and requires OpenGL hardware acceleration for optimum performance. If you don't have it, you'll see a pitifully slow framerate. This saver is freeware, so there is no support available for it, but feel free to send comments and suggestions to me (Terry). Contact information is available on my website: http://www.reallyslick.com Installation instructions: 1. Extract the files from this .zip file using your favorite zip program (you should have already gotten that far or you wouldn't be reading this). 2. Place the .scr file in the directory that contains all your other .scr files. This directory varies between versions of Windows, but it's probably something like "Windows/System32/" If you can't find the correct directory, go to the "Start" menu, click on "Search," and perform a search for .scr files. 3. Open your "Display Properties" window by right-clicking on your desktop background. Click on the "Screen Saver" tab and select this saver.
