My banner image is adapted from a Golgi stain from Flikr user httf, whose other work is also pretty cool, by the way. I started by applying some effects filters in PowerPoint 2010 (surprisingly enough), and blended the results in GIMP. That’s the Gnu Image Manipulation Program, not an epithet for the disabled, but in fact one of the most powerful free applications around.
