Believe it or not, this tessellation is closely related to my Double Spearhead Tessellation.

The idea came about when I was teaching the latter at BOS50 and one of the participants (whose name I unfortunately do not remember) made a mistake. I pointed it out but also remarked that it could be an interesting variation. After getting home, I worked on the molecule and ended up with this design. The molecule uses an 8×8 grid and the whole model uses a 32×32 diagonally rotated square grid.

The name is Latin and means “happy fault”. It originates from a religious context (God can turn even a grave evil into something good) but here I used it because of how the model came to be (an error made during a workshop turned into an interesting new design).
