Logo Saver is a screen saver module for OS X that displays text randomly over your screen, you can choose to fix the text colour and font/size or have the text colour change randomly. It also displays a picture of your choice and can optionally float that over the screen while bouncing off the edges of the screen. You can also choose to have the text swap for the picture and vice versa - a timer is provided for this functionality.
