Simulacrum and Simulation
And where would we be without a computer to do all the hard work?
I think we’re all convinced that a computer is necessary, but if you’re not I challenge you to do it yourself. It takes all of one minute to find a ball and book. Try to keep the ball ontop of the book. Did that work? Good, now try to make it stop. Exactly where you want, to +-5mm. If you get that far, now try to make it roll down the edge of the book. Still hanging in there? Now, make it trace the contours or your favorite Van Gogh painting. The Scream should be a good one.
