Here are some old images made with Pan. Each thumbnail image below is a link that will take you to a larger version. Placing your mouse cursor over a thumbnail will show the defining formula and the size in bytes of the larger image. For many more examples, see Functional Images.

Yet to come: more image filters, 3D, sound, and more animation.
