reminds me of these symmetric 2D P3 lizards:

I bought the RGB-coloured set/puzzle after visiting an Escher
exhibition and sometimes use them in crystallography/symmetry teaching.
Nice to make the students assemble them and then decide on the
symmetry operator, unit cell and asymmetric unit.
Quoting Phoebe Rice:
Hi all,
For those who teach xtallography - we found some plastic turtles
that can be snapped together in an amazing variety of space groups.
Worked well in a workshop for our students, so I thought I'd share
the shopping tip. They're called Reptangles, and we got them from
Amazon.

Have fun!
