This is an idea for an art installation.
Dozens of volunteers hold their arms up through closely-spaced holes in the floor of the room. You cannot see any part of the volunteers except their arms, which appear to be growing out of the floor. Each arm is sleeved in a different, random colour.
If not otherwise occupied, the arms sway from side to side, gently feeling around them.
A hundred-dollar bill is being passed from hand to hand all around the room.
Visitors to the installation may walk through the sea of arms.
