This artwork shows a configuration of Desargues' theorem drawn on
a Boy surface. Gerard Desargues is a 17th century mathematician,
whose work laid the foundations for projective geometry. The
theorem named after him describes the incidence structure of two
triangles in the projective plane. At the beginning of the 20th
century, Werner Boy discovered an immersion of the projective
plane into $\mathbb R^3$, now known as the Boy surface. This
artwork builds a bridge over 300 years of mathematics. The white
structure corresponds to the Boy surface, on which are drawn two
triangles (in blue and purple) satisfying Desargues' theorem: the
yellow lines meet at the center of perspectivity while the brown
line is the axis of perspectivity
