G E B upper (2x2x2)

The GEB models are a tribute to the shapes featured on the cover of Douglas Hofstadter's book "Gödel, Escher, Bach: An Eternal Golden Braid". These "trip-lets" come in two different shapes for the upper and the lower position and in three sizes. High-resolution pictures can be found at https://flic.kr/p/5StVjJ, https://flic.kr/p/5TfkzR, and https://flic.kr/p/5WdB79. This particular one is the upper piece and with 2x2x2 cm the small size.
