Circular Saw (Escher / Droste Style)
This is a photo of one of my circular saw blades (DeWalt 36 tooth tungsten carbide finishing saw, to be precise), distorted with MathMap. I liked the yellow paint on the blade edge since this is a fresh blade.
strobist: 1/4 power Sigma EF-500DG Super, eBay trigger, diffused
through white plexi--to get a nice specular sheen on the brushed steel--against velvet (my poor homage to the lighting work of ming thein's timepieces).
See it large here.
