How does this Work??

All you smart people, how is this done ?

1) Go to the link below. After reading each window, click on the boy in the lower right corner of the picture.
2) In the last window type in your answer in the white box using the keyboard (there is NO cursor).
3) Watch the paper in the boy's hand. You will be amazed . . .
and, if anyone can figure it out, please let me know in the comments section of this post.
