Sierpinski White by Tibor Lantos of FontShop International GmbH is a free geometric outline display font built from nested triangular linework. Its angular letters resemble tessellated diagrams, with open interiors and clusters of triangles creating a mathematical texture.
A science museum poster is an apt setting, since the fractal construction turns lettering into part of the subject. It also suits mathematics publishing, puzzle games, and technology graphics. Across applications, the repeated motif links words with diagrams and rule-based systems.
