A spectator is asked to think of any card, an absolutely free choice. They are then given eight specially printed 'computer cards', each with some random card pips printed on them. The performer requests that they look through the 'computer cards' and retain the ones that have their thought of card. The performer instantly reveals the selected card.

This amazing trick is incredibly easy to perform.
