GL Screensavers 1.0

The GL Screensavers package contains 5 OpenGL 3d screensaver modules ported to Mac OS X from the XScreenSaver distribution. To install them, open the "Modules" folder in the disk image and copy the files in that folder to the "Screen Savers" folder in the "Library" folder of your home directory. (Create the "Screen Savers" folder if it does not exist). After you do this, the screensavers should appear in the "Screen Saver" pane in System Preferences. Additionally, all the screensavers have been verified to run well in SaverLab. For best results, Mac OS X 10.1 or later and an OpenGL accelerated graphics card are strongly recommended.

The following is a brief description of each screensaver module:

Impossible Cage: Displays a rotating cube whose edges cross each other in a physically impossible manner.

Circuit: Displays moving and rotating electrical components such as resistors, chips, and LEDs. You can configure the number of pieces and whether they spin as they move.

Infinite Stairs: Displays and rotates a staircase whose stairs appear to be constantly ascending.

Moebius Ants: Displays a Moebius strip with ants marching on it. Configuration options allow you to display a solid or wireframe strip and to hide the ants.

Rubik: Displays a rotating Rubiks Cube which repeatedly shuffles and solves itself. You can configure the number of random moves made when shuffling, and change the size of the cube up to 8x8x8.

By default, on multiple monitor systems only the main monitor will run the screensaver; others will be blank. If you check the "Use All Screens" checkbox which appears in each of the configuration sheets, the screensavers will run on all screens. Generally you should not run on all monitors unless all of them support OpenGL acceleration.
