Description: sea biscuit Apparent size: 3.5 mm Common features: star patterns, pentagons, and hexagons cover the surface of this organism |
 |
| Stacked frames: 5
Enhancement methods: bright/contrast difference anti-shadow After bright/contrast, five frames were stacked and the differential process done. The resulting image had anti-shadow algorithm applied and then contrast enhanced again |

Summary description of image contents: an organism similar to a sand dollar, this is an excellent and detailed view of overlapping geometric patterns. The five-fold symmetry and regular pentagons are not found in mineral crystals, and have only recently been synthesized in "quasi-crystals", after the work of Roger Penrose. Biology is the only known non-man-made example of pentagonal structures in nature.
