Statement

I am interested in the intersection of creative art and mathematics, and in showing through my work as an educator that these are not opposing ways of thinking. In this piece, I constructed a pattern, hidden on a 12–6–4 tessellation, and decorated its surface with watercolour and gouache. I am drawn to the different purposes of decoration in geometric art: to bring attention to the surface, to reveal structure, or to deliberately conceal it. Small decorative choices, colour shifts and repeated motifs, create flows that echo the underlying grid or disrupt it. Through this process, I explore how decoration shapes what mathematics becomes visible, and what remains hidden.

A hand‑painted geometric composition constructed on a hidden 12–6–4 tessellation. Watercolour and gouache are used to decorate the pattern, exploring how ornament can reveal or obscure the underlying structure.
