A vector based font can be summarized by a few parameters. Here I have made a vector based font where the parameters are the input to a physically based simulation of a bouncing ball. A visual theme of the letters emerges since the same physical model is used for all characters in the font.

In this applet you can enter text and see it appear in the bouncing ball font. You can also edit individual characters of the font on the edit screen by either moving the scroll bars or clicking the mouse in the drawing area. Then you can return to the layout page and see the new characters in a page of text.
