Block Fractals

Exercises

1. (a) Build a model of the third stage of the four-block configuration.
(b) Compute the dimension of the limiting shape. From this, conjecture which measures are infinite and which are zero. (Here is the answer.)
(c) Compute the perimeter of the limiting shape. If we expect the perimeter is infinite (from the dimension results), we might simplify this computation by finding a family of perimeters contained in the perimeter of the corresponding levels, and having an infinite limit. Perhaps one of the pervious perimeter computations will be useful. (Here is the answer.)
(d) Compute the area of the limiting shape. (Here is the answer.)
(e) Compute the volume of the limiting shape. (Here is the answer.)
(f) Interpret these computations using the dimension. (Here is the answer.)

2. (a) Build a model of the third stage of the five-block configuration.
