Rock-paper-scissors is a hand game played by at least two people. The game is also known as roshambo, or by other orderings of the three items (with "stone" sometimes substituting for "rock")
Watching the 3 items here, the rock, the wood, and the grass, all three in this natural setting, I couldn't held thinking of the rock-paper-scissor game - though the items are not the same. :) PS: Of those 3 in my picture, grass wins.
