Snowflake Wall of Shame
This page forms an addendum to the MPhys project I ran on the symmetry of snowflakes. See the final report of my student John Watts here.

It seems that even the idea that snowflakes have six legs is not universally accepted. Here are a few examples from the other camp, some of which violate the Crystallographic restriction theorem. If you have any additions I'd be happy to add them.

Finally, a reminder to be critical whenever a theorem is quoted at you without proof:
