From the doc: 'Launch The Finger on an unsuspecting user and watch their reaction when the cursor changes to the middle finger and then back to normal again. By default The Finger will switch the cursor to a finger every 5 seconds, but you can configure how often the cursor will change by passing the word 'setup' on the command line. Closing this program is now easier then ever, just move the mouse cursor to the top-left corner of the screen and it will close.'
