Looks like another way of tapping into the (modern) subconscious mind (cheaper than drugs or alcohol) but still on par with the Ouija board or automatic writing. like PP I wonder what a true random selection done by a computer would come up with. Someone once explained to me that the human mind when asked to produce a random selection actually does the opposite. If asked to fill a square on paper with random dots people dustribute the dots evenly over the square where as if the dots are generated truely randomly they will be grouped in clumps with spaces between them and may even appear to make patterns to the human eye. We are desperate to make patterns and sense when there is none.
