|Each Pan picture in this collection is based on a simple combination of disks.|
|Start with a number of disks in a row.|
|Next, progressively shrink the disks and the spacing.|
|Finally, rotate each disk further about the first one.|
|If we bring the disks together closely enough, they will show white instead of black at their overlap.|
When brought together even more tightly, we see the general coring rule. The disks appear black where the number of overlapping rings is odd and white where even.
