Generic Screen Saver for Mac

From Scotland Software:

Generic Screen Saver is a Mac OS X screen saver which lets you display some text or an image of your choice, moving around the screen randomly. You can choose:

• The text to show
• The image to show
• The delay before moving the text/image to another location
• The text font, size and color
• Whether or not to also show an URL of your choice
• When to show the URL

It's useful for making a basic screen saver with your own company information, a favorite quote, a picture, or whatever you like.
