What happens when you take a bunch of auto-generated tests and test results which you burn into rasters with SQL? You get a code fingerprint of sorts. Well that was the dream I wanted to explore. Now that PostGIS 2.0 has introduced a new spatial type called raster and lots of functionality including some very cool Map Algebra functionality to go with it, this is now possible without too much fuss. My first attempt at it didn't produce quite what I expected. I have to admit it is absolutely gorgeous and will be hopefully useful once I figure out how to read it, tweak the rendering process to achieve more of a breakout of results, or patent it as a fabric style.
Now for the story of how a disturbed nerd is born.
