Desktastic

Desktastic is a utility for Mac OS X that allows the user to actually paint on the desktop or any other window, as opposed to in a standard window. It implements a little sidebar on the screen where things like colors or tools can be chosen. Desktastic can be used to draw, doodle or even to write things down.

Desktastic is available as Shareware and can be used for a time period of fifteen days. After that the user has to purchase a license for $12.95.
