Notes:
We love optical illusions. Check this one out!
A confession: This design was inspired by an image generated by Paul Nasca.
I needed an algorithm to position the light and dark disks, so I got out my trusty Calculus book to find a mapping that created a ripply surface (cuz Paul's circles looked ripply to me) and used that surface to create positional angles at each (x,y) coordinate for the light/dark circles.
This current design is not as ripply as Paul's but it is a start!
This project actually inspired the creation of the TNTShadowedDisk.
The design to get the ripply effect is shown in the Swimmy Circles Topo Map in this design library.

Made use of the 'translate' function for TNTPoints. |

var angle = 360 * Math.sin(.002 * (x * x + y * y));
angle = Math.abs(angle);
var delx = offsetRadius * Math.cos(angle * Math.PI / 180);
var dely = offsetRadius * Math.sin(angle * Math.PI / 180);
