To quote Don's paper on PSIBER Space:
"When you mouse ahead through a pie menu selection quickly enough, the
menu is not displayed, and the shape of a pac-man briefly flashes on the
screen, with its mouth pointing in the direction of the selected menu item.
This "mouse ahead display suppression" speeds up interaction considerably by
avoiding unnecessary menu display, and makes it practically impossible for the
casual observer to follow what is going on. The flashing pac-man effect gives
you some computationally inexpensive feedback of the menu selection, and reas-
sures observers that you are racking up lots of points."
"This paper will be presented at the 1989 Usenix Monterey Graphics workshop."
