Tutorial: Jigsaw using ActionScript 3.0.

Note that checking for completion in both programs is done with a tolerance factor: the
player does not have to be perfect. If you want to make the puzzle more challenging, you
can decrease this factor. If you require the player to position things exactly to the pixel, it
will be very difficult to complete.
The third version of the jigsaw has something called an attractor or idler. The game
begins with the pieces periodically in new, mixed up positions. When the player starts to
drag a piece or clicks on a button, the pieces stop moving. If the player does not do
anything for a certain period of time, the pieces move again. The idea here is that this
application could run on a kiosk and 'attract' people passing by. The term idler comes
from the notion that the game is idling. People build idler/attractors that have no
connection to the actual application. For jigsaw, mixing up the pieces is an obvious
choice for the idling display.
Overview
The critical parts of building this application are
creating the puzzle pieces, including determining the information that needs to be
stored in order to re-create the puzzle
