Several years ago, I created a personalized version of the Nittany Lion to use as a filler in ETS publications. The image was never officially sanctioned or approved. Though the image seemed to gain a small amount of popularity, without official approval it couldn't be developed into a useful identity piece. Kind of sad, really; I think the characterization had potential. You can still view and download these old lion cartoons along with any others I may develop. The sanctioned versions of the Nittany Lion caricature are available from the Department of University Publications.
Examples of my work are currently in four sections, available with these links or the same links in the left hand sidebar. My most recent work is digital:
