Dollar Bill Eye of Providence
This is the Eye of Providence (en.wikipedia.org/wiki/Eye_of_Providence) from a one dollar bill.
To add to the technical details found in the EXIF data:
Not cropped beyond a 2.3 degree rotation.
A set of 3 extension tubes (12mm, 20mm and 36mm) was used to get some magnification.
Biggest problem is camera shake. The thing bounces around like it's in an earthquake whenever I touch the controls to focus.
