Thanks to Nicholas Exner for this nifty puzzle applet.
Description and Instructions:
Examine geometry first hand by using this web activity to solve the problem
of creating five squares by arranging twelve toothpicks.
To move a toothpick, click on it with the mouse and drag it to the desired
location. You may also rotate a toothpick by 90 degrees if you click
on the toothpick and then press 'R' on the keyboard. When you
are finished creating the five squares, be prepared to describe to others
where each of the five squares are.
Clue: A square doesn't necessarily have to be 1 x 1 toothpicks in size.
