A Darwinian image of a speck, a mouse, a monkey, a human, and a computer. Optionally, several computers, each exponentially larger with the last going completely off the edge of the page (i.e. building sized). Optionally, with the brains highlighted in some sort of x-ray kind of view.

Edit: Nevermind, I see this is a listed cliche. Well, it's cliche for a reason.
