You will need the following materials to make and present this illusion:

1)  Several sheets of 8.5" x 11" printer paper
2)  Scissors
3)  Masking tape or transparent tape
4)  1 clear, tabbed sheet protector
5)  A drawing software program on your computer that has a gradient tool.  I used Photoshop CS3, so I will give clear-cut instructions based on that software.
