Statement

I am a mathematician at the University of Galway, with artistic and scientific interests in the craft form of tessellation origami. I am especially interested in the use of origami as a practical tool for exploring phenomena of discrete geometry, such as the wallpaper classification. Through my work in this field I try to highlight the power of art as a means for expression and appreciation of mathematical meaning, which is underutilized both in mathematical research and in education.

Image for entry 'Buí'

Buí

42.0 x 42.0 cm

Paper

2026

Additional info

Buí (pronounced "bwee") is the word for yellow in the Irish language. This origami tessellation has three distinct views: opaque views of both front and back, and a backlit view that highlights the pattern created by varying numbers of paper layers. Please pick it up and look from both sides, and hold it up to a light source in the room for the backlit effect. Each of the three views shows a plane periodic pattern plane with four-fold rotational symmetry. The four-fold rotation centres are at the same positions in all three views. The patterns in the three views represent the three distinct wallpaper classes whose symmetry groups include four-fold rotations, and the backlit version may be interpreted as a superposition of the other two.

Bán

42.0 x 42.0 cm

Paper

2026

Additional info

Bán (pronounced "bawn") is the Irish word for white. This origami tessellation is a companion to Buí. The front, back and both distinct backlit views show periodic plane patterns. All four views show patterns of the same wallpaper class (p4m or *442), with rotation centres and reflection axes in the same positions. The work is a single intact piece of paper, folded by hand from a 70cm square sheet.
