Big Cats Screen Saver (12 images) displays images of big, wild cats which can be displayed using a variety of 2D and 3D graphical effects. You can choose from eight different screen saver routines: 2D Sliding Tiles, 3D Flying Tiles, Flying Puzzle Cube, Blocks' World, Wipe Out, Bouncing Balls, Slide Show, and Combo (a combination of all these routines chosen randomly for each image). It includes various options that let you select the image resolution, adjust the effects' speed and size, display a border around the images, use over 100 transition effects, show an analog clock on the screen, include a floating text box with a description of a given image, and set the time delay between images (in seconds). The screen saver also supports MID and WAV sound files, enables you to use your own BMP and JPG images, and includes a wallpaper option that allows you to display a new background image every time you start your computer.
