This screen saver 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. Since this screen saver is shareware, I ask for $5 if you decide to keep it. The address to send the money to is available in the saver's settings menu. It's only shareware, so there is no support available for this saver, but feel free to send comments and suggestions to me (Terry) at mogumbo@fcmail.com INSTRUCTIONS: Just extract the .scr file from this .zip file using your favorite zip program. Place the .scr file in your Windows\system directory (Win95/98) or Winnt\system32 directory (WinNT). Then open your display properties window and you can activate this saver.
