I found this awesome comic by cartoon by Dwayne Godwin, a professor of neurobiology at Wake Forest University, and Jorge Cham, the former researcher and cartoonist who created PhD Comics; it actually won the the informational graphics category of the 2009 International Science and Engineering Visualization Challenge.  Must print it out 🙂  Visit Godwin’s public engagement page, where it and some others can be downloaded as PDFs.
