Unless I am very mistaken this is more and more terms of the Fourier series (in polar coordinates). The disks seem to indicate the magnitude of the terms of the series (but there seem to be too many disks for my feeling after the first go-around is finished). One of the many many cases where people really should indicate what they are doing when putting pictures/movies online. Best regards, jj

Does anyone have "favorite" examples of a cool mathematical picture or movie that cries out for (but seems to be lacking) documentation? One of my ideas for Mathematical Enchantments is writing explanations of cool stuff that's already out there in visual form, in addition to my practice of writing essays on a pet topic of mine and then looking for someone to illustrate/animate it.

How about a collection of blackboard/whiteboard drawings, such as the Sullivan-Thurston Jordan curve in http://www.math.tamu.edu/~manshel/Riverside/m10B/Jordan-curve-diagram.pdf Invite your math friends to submit photos. -Veit
