Recently I was lucky enough to have a digital artwork included in ANU's course materials. T'was all thanks to an ANU senior lecturer and Associate Director of Science Education, Lindy Orthia.
It's a little hard to tell, so here's a clearer version below. The candle aspect is a reference to Carl Sagan's The Demon-Haunted World: Science as a Candle in the Dark, and the art style is charcoally cave-painting.
I tried to give equal weighting for the 'sciencey' imagery, but my background in biology is obvious.
