Our plan started as we wanted to have a beam in between two thin cardboard boxes that moved back and forth with three salad fingers on it. We’d put down a piece of paper in between the two boxes and put paint on the fingers. The fingers would move back and forth on the paper making paint streaks.
We tried making the fingers by wrapping tin foil around a paint brush and painting the foil green, but it was difficult to completely cover the foil because it was so crumpled up. So we decided to rethink our plan.
