Moiré fringes are an optical illusion created by interference between two repetitive structures. The geometric distribution of dark and bright areas in the superposition are extremely sensitive to the slightest displacements of the sheets or movements of the viewer.

The work originates from a cross-disciplinary course Crystal Flowers in Halls of Mirrors: Mathematics meets Art and Architecture held in Aalto University.
