This page creates 3D models that cast shadows in the shapes of three letters. You can customize the letters, interact with created models and download them for e.g. 3D printing. These shadow cubes are known from the cover of the Gödel, Escher, Bach book. Up to 12 distinct configurations will be generated. The font used is Gotham Black Regular.
Note that the models are created server-side and the process can take up to 20 seconds, based on many factors. Please be patient.
