| Before we get into the real details of the routine, let’s look at what the audience |
| sees and go over a brief description of how the effect is accomplished. Matrix begins |
| when four coins are placed on the table in a square array (or matrix). Let’s |
designate the positions of the coins as Upper Left, Upper right and so on.  A card |
| is placed on top of each coin. The performer commands one coin to move, and then |
| two cards are lifted to show one coin has disappeared from under one card to find its |
| way under the card in the upper left hand corner. This is repeated with the other two |
| coins until all the coins have gathered under the upper left hand card. |
| The main move occurs while the right hand, holding four cards, thumbs a card onto |
| each coin. As the second card is placed on the table, the fingers of the right hand |
| secretly pick up the coin there. Then as the third coin is covered, the concealed coin is |
| allowed to fall under the card. The fourth card is placed on the coin at the lower left |
| position. Thus, a coin has been moved from the lower right position to the upper left |
| position while the coins were covered. This one coin is a one-ahead device to achieve |
| the following three transpositions. |
