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.
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
Does anyone know where one can acquire some Penrose tiles? I think
they'd be great toys as well, and drive you a little bonkers. Maybe a
kitchen/bathroom floor made from them?

Thank you for the info. It looks great for teaching or for just having fun.

If you go to froogle.google.com you will find that you can
buy these at a noticeably lower price than at amazon.com,
at least for people in the USA - just search for Reptangles.
