Update on new technologies, thanks to my friend Nick.

http://www.dedoimedo.com/computers/mandelbulber.html Mandelbulber is open source software for visual rendering of 3D fractals. The 2nd image on the Web page reminds me of pollen. If there were a 3D printer that could make objects sufficiently small, it MIGHT be possible to develop a non-allergenic vaccine against hay fever and asthma.

http://www.micronautomata.com/ This is a totally new hardware architecture that could vastly speed up the digitization of complex objects such as real life pollen, that approximates a 3D fractal.
