PFiddlesoft (http://pfiddlesoft.com/pfiddles/) has released Waccy Accy 1.0, the second application in the PFiddle Collection. It’s an US$4.99 game based on Apple’s Accessibility API (application programming interface). A 30-day demo is available for download.
To win Waccy Accy, you reveal your full user name by flipping the placards displaying placeholders so they show their hidden characters. You fill in the blanks by moving the mouse pointer over text elements on the screen containing the missing letters.
The more you play Waccy Accy, the more familiar you will become with where things are on your desktop. You play against the clock, and your best time is recorded for posterity.
