In the paper, Althöfer describes games/research that you, too, can play/research. Instructions for Lego washing roulette: Make your own brick combinations. Then dump a bunch of individual Legos in the machine and see if you guessed what would appear. Most complex guess wins. (Althöfer reports no success with this method.) Or, build something with multiple bricks stuck together, toss it in the machine, and if it doesn't collapse during the spin, you win. Or, best of all, play your very own game of Lego eugenics!
