Oh, the hilarity of Tim Davis's self-referential My Audience project.
Observations from a recent lecture at Hamilton College:
Prior to beginning [the] lecture, Davis insisted that all audience members be seated in the middle section of the [lecture space], where nearly all seats were quickly filled. Rather than starting his talk, he began adjusting a camera that stood on an impressively large tripod. He took three photographs of the audience, requesting that each member look as though they were sitting in an incredibly boring lecture.
His first few slides continued on the subject of why he photographs those who attend his presentations. Davis showed numerous photographs of past audiences while explaining that, in this way, he gets to continue his work even when giving speeches. In this way, he never has to leave the craft that he loves. (Hamilton College News)
