Quite a lot has been done already; I'm hoping that the piece might be around 2 minutes long. I'm planning to document progress here, and invite feedback from readers.
This image is from an earlier test. It suggests some of the themes and techniques I'm pursuing. The movie would represent a journey through space and time, a road journey encompassing all human evolution from nomadic wanderers to city dwellers. A kind of 'uber timelapse' compressing tens of thousands of years into a couple of screen minutes. All elements would construct themselves on screen and possibly be represented in a multi layered or stratified form.
