After seeing the Swinging Sicks Kinetic Energy Sculpture on Ironman 2, I thought it would make a decent clock.
Tools used: drill, saw, tap, scissors, and a round file, nails. W/ a few other as you can tell.
Materials: Quartz clock movement, 5"X6" wood plaque, Wood sticks 1/2"X1/8"X2', wood dowel 1/2" round X5/8" long, non-insulated connectors, rubber band.
I got the measurements for the sticks from: bloomautomatic instructable
http://www.instructables.com/id/Iron-Man-2-Swinging-Sticks-aka-Double-Pendulum/
I cut sticks and dowel to length, Drilled holes for hour hand movement to a small piece of stick with dowel nailed to small stick and hour hand. Used connectors for my pivot points with a piece of nail though hour hand to act as an axle(needed to keep it from twisting due to rubber band I used as the belt made it twist out of shape.

So is that actually a functional minute hand? It's hard to tell from the pictures. Does it accurately do 360 degrees every hour? That' s a really cool idea!

It does make the 360 every hour. It's not accurate as it would be as a high torque movement would be, But I didn't want to wait for one.

Ohhhhh, now I get it. The minute hand is driven by the minute hand axle on the movement. It seems like a lot of load for a typical quartz movement. What model/make is the movement you used? Or where'd you get it? Is it designed for heavy clock hands? Thanks

I got the movement from hobby lobby, although it's not high torque it still works, just not as accurately.
