Marty is an avatar playing in the OSU (Open Source Universe, sometimes Open Source Unversity when describing its use as the successor to the public education system). He's not paying attention, and he's about to discover what the insides of a red-tailed hawk are like (he'll especially enjoy learning about the duodenum).

This image was a "proof of concept" for a possible web comic about Marty's adventures. I anticipate this setting to be recurrent in the future, along with Welcome to Heck, and others.
