Project 4 Idea

For our open project, I want to make a clock with visible gears behind it.  I want to show the passing of time by using these gears as ways to mark decades.  I will have a large gear with an important image from that decade with smaller gears surrounding it with other significant images from that decade.  I think I will do the last four decades, the 70s, 80s, 90s and 2000's.  The piece will be 3D, with the images mounted on matboard and then layers on top of each other with a clock on the very top layer.

This is an example of one I found online and my inspiration:
