This applet tests the user's typing abilities, especially when "touch typing". As the user types, the letters show up in random places on the screen. This makes the typed text very illegible. In order to increase the legibility of the text, the user can use the "expand" button. This will cause the scattered letters to be drawn closer to each other. Eventually, the optimum "expand" state is reached when the typed text is rendered in its regular form. The "reduce" button causes the letters to gradually go back to their scattered placements.
