Did you know that you can display your own images as part of the '3D flying objects' screen saver? This is helpful if you want to display your corporate logo as the screen saver, for example.
To do so, go to "Display Properties" and then to the "Screen Saver" tab. Choose the 3D Flying Objects screen saver and then push the "Settings" button.
Change the object style to "Textured Flag" and then click the "Texture" button.
Now you can select any *.bump file as the image.
