A method of determining the toxicities of chemicals involves recording and analysis of spider-web patterns. The method is based on the observation that spiders exposed to various chemicals spin webs that differ, in various ways, from their normal webs. […] The more toxic the chemical, the more deformed a web looks in comparison with a normal web. Inasmuch as the shape of a spider web resembles that of a crystal lattice in some respects, techniques of statistical crystallography are applied to obtain several quantitative measures of toxicity as manifested in the differences between photographs of webs spun under toxic and normal conditions. The images of the cells are digitalized and processed by an image-data-analysis program that computes various measures of the cellular structures of the webs, including numbers of cells and average areas, perimeters, and radii of cells. It appears that one of the most telling measures of toxicity is a decrease, in comparison with a normal web, of the numbers of completed sides in the cells. […]’

How fantastic would be if real estate could also be patternized in the same way, detecting constructions that were carried out by humans intoxicated by speculative money flows, high on political power, boozed up on controlling an occupied territory or just a bit tipsy for destroying natural landscapes…

Thanks, edu!
