"The shape of the flowchart can be the joke in itself. At Skull A Day, there is a new picture of a skull posted every day. The webmaster created a flowchart that detailed the process of deciding how to create or select the skulls. Click the link, then click on the image for the larger, readable version. The chart itself is in the shape of a skull, so there’s one for another day!"
