Do you sometimes lose you cursor when mousing around the desktop? You can make you cursor larger and easier to find. Choose System Preferences from the Apple menu. Select Universal Access. Click Mouse, or if you have a MacBook, click Mouse & Trackpad. Finally, just drag the Cursor Size slider to the right to make it larger.

On MAC OS X Ver. 10.3.9 there is no such thing as a cursor size slider in the Mouse tab of Keyboard and Mouse in System Preferences.
