# Lisa Kattchee and Karl Kattchee

This brother/sister collaboration is based on the premise that mathematics and art are inseparable and they interact on many levels.

Each of the images in this array is a collage, created using the
editor at polyvore.com.

Each image in this 4x4 square has a mathematical theme, such as
symmetry, cardinality, trigonometry, topology (donuts and Klein
bottles), fractal geometry (Mandelbrot set), self-reference,
infinity, etc.

Two of the images are derived from mathematical art previously
exhibited by Karl at the Joint Meetings.

The overall image is a magic square, although the metric for
evaluating the rows and columns will remain unexplained.
