So now you can see that cartoon people and organic people respond differently when run over by construction equipment. While the organic person did lose some depth, he did not end up entirely two dimensional like a poster. He probably won't pop up again either.
It looks like the victim was guiding the machine to keep it away from the retaining wall. He was suppose to stay ahead of it but got too close. The track caught him, pulled him down and the machine was on him before he could even scream. By the time the track-hoe stopped, he was already directly under it. The operator quickly backed it up. But the guy was squeezed out like a tube of toothpaste. He died almost instantly.
I think the man at the right is the foreman. He appears to be telling everybody to get back to work while silently wishing he could just cover the mess with dirt and keep going.
