Just as a tangent: what you posed is an example of what the magic community refers to as a problem (what the spectator sees). Magicians then try to come up with a method that satisfies all the constraints specified in the problem.
Slightly more annoying though is that I seem to have forgotten to add a website I found last time I researched "mind reading" to my bookmark collection at pinboard.
