As someone with a passion for the visual arts, I've long been fascinated by tilings, photo-montages, and the ways in which our brains process visual information. As a mathematician, I am familiar with the joy that comes from the hard work of solving a difficult problem. With my art I hope to present viewers with patterns and symmetry from pure mathematics, to convey a sense of wonder in its intricacy and scale, and to challenge viewers to make sense of what they see.

The image pictured under the eyeglasses is the unique solution to the all-ones problem on a 127 x 127 grid: the black squares indicate which buttons to push to solve a Lights Out game if initially all lights are on. The solution comprises two distinct regions. The contrast between them is emphasized by the placement of the eyeglasses, which introduce a third dimension. It is a human dimension, suggesting both the power and the limits of mathematical insight and understanding. These layers of ambiguity invite the viewer to discover meaning in the patterns.
