Zener Cards Test
written by New Line Productions, Inc.(?) from their Final Destination movie site

You will be given 25 opportunities to predict the correct symbol. Your total out of the 25 tests will determine your psychic powers. There is a 1 in 5 chance that you will guess the correct symbol, so a score of 5 would be attributed to chance. A score of 6 to 10 could be attributed to some level of psychic ability, though more likely you could be luckier than most. A consistent score of 10 or higher and you may have some form of psychic ability.
