Here's an online magic trick. Even though you're at home, the Magic.about.com web site is going to track your every move.
Please select one of the four shapes shown here. The easiest way to experience this trick is to place your finger on the screen and point at the object.
On the next page, you'll be asked to count and move from shape to shape. You're free to move up and down or right and left, and it's okay to repeatedly move between two shapes. But please don't move diagonally or off of the page to the other side. Click with your mouse to continue.
