Flyphabet was a children's alphabet game I devised as a prototype application for Philippe Piernot's novel 2D spatial input device. In the game, a number of flies descend on the user's collection of food, and attempt to fly away with an item. These flies are lettered, such that taken together they spell out the name of the item they are attempting to steal; the user's objective is to splat the flies in order — correctly spelling out the name of the item — before the flies carry the item away.

In the screenshot below, flies spelling out the word "apple" are attempting to make off with one; the user has made a good start at preventing them. Phillipe implemented Flyphabet in Macromedia Director.
