On your Desktop you normally have a picture or something that serves as the Background to you desktop space. On a PPC you have the same thing called the Today Screen which serves to show you important info such as upcoming appointments, the owner's information, and other misc. information. It can be quite dull if you don't add some pizzaz to it. Windows mobile gives you an easy way to do this by giving you the choice to use an existing picture as the backdrop to your today screen but there are other alternatives some free and some not.

The website PDA and Mobile Today has put together a collection of some pretty nifty today screens. Check it out at PDA and Mobile Today.
