I'm with drewbee on this one. The typewriter icon is apt for Formulate. I can 
remember, many times, getting to the end of a page of typing and discovering an 
error that was beyond Whiteout and having to trash the whole page. The digital 
world was supposed to represent an improvement over those days.
