The challenge: find the simplest way to cover as big an area as possible in as little time as possible. We spent about 2 hours and covered perhaps 600 feet. I love the simplicity- creating forms simply through following a theme.
A response to the challenge: create a design that could be repeated endlessly, uniting the beach. 3 of us took about 2 hours to get a little ways down the beach. With a bunch more teams this would work for as big as I’d want.
