a friend in my biochem lab convinced me to try an esp expriment he found online at http://sprott.physics.wisc.edu/pickover/esp.html. although a skeptic myself, i found it difficult to laugh at the "experiment" after a few tries.
i am aware of many mathematical tricks (most of them trivial) with which performance "magicians" fake mind-reading, but this one utterly escapes me at the moment ... could it be the real thing?
since i have access to at least a few hundred human brains with above-average intelligence and acute discrimination, i've decided to distribute this problem for parallel processing. hope you have fun with it.
