In Japan, if you want to assign an order to something randomly, you use one of these decision maker doo-dads. It works surprisingly well. Let's say you're assigning speaking order to a number of speakers at a public event. First draw a number of vertical lines, and label each one with a speaker's name. Assign the speaking orders available to the bottom of the lines. Then randomly connect each of the vertical sticks with some more-or-less horizontal lines. These can be truly level or rather off of level. Starting with the first line on the left, follow the line down until you hit a horizontal line. Then follow this to the next vertical line and go down that line until you once again hit a horizontal line. And repeat. You must always change course when the line you're following intersects with another line. You'll find yourself traipsing through the thing in a way that gives each speaker a unique speaking order. Done!
