I've long been very curious how one would generate a reasonably good source of randomness in a practical way without using a computer. Perhaps one could think of a song and then try to deduce randomness from the first letter of each word. I haven't found a way yet, any ideas?
I occasionally want to use a reasonably good source of randomness when e.g. picking a board-game player or picking a random item on a menu.
