Chaos with Christmas ornaments (Score 1)

If you stack four Christmas balls in a pyramid (like cannonballs) you can "see the Chaos" inside them in the form of a fractal basin boundary.

This boundary has the "Wada property" which makes the IR beam spread throughout the room. To demonstrate: (1) take a laser pointer and sight over the top of it to aim the beam at the fractal: the beam will be visible through all of the openings (2) aim so that you miss the fractal pattern but still hit the balls and the beam on exits through only one opening.
