The Sand Dollar is an iteratively constructed radial form using the Sand Stroke painting technique. A very high level of detail is achieved with backpainting each Sand Dollar several times. The radial form is constructed with a sweeping tree-like structure that oscillates as it moves clockwise around the origin. Attached to the tree in random locations are the Sand Stroke elements.

1003 Unique Every sand dollar is the product of over 16,000 random events.
Hundreds of thousands of Sand Dollars have been generated by the programmer over the course of many days. He does not understand why he does this.

Some may notice that each sand dollar contains a flaw in the radial symmetry. This flaw is an artifact of the pixel exposure construction process. It could be removed with some special case algorithms, but the programmer found it enjoyable, and left it in.
