Digital Timepiece: a note on the header image

I was searching on internet for images that might be appropriate headers for our Digital History Working Group website, and I came across this page. It is an online book called Digital Timepiece by Nathaniel Haefner, which is organized around different ways of thinking about time and storytelling. I’m happy to change it if someone has an image they prefer. But it is an appropriate beginning to our endeavor, no?
