These were made by Robin Wang - a customer and student here: She says:
"Here are a few pictures of my Swarovski crabs. The small ones are quite small... mostly made of 3 mm bicones."
I think they are totally awesome - they actually were part of her contest entry to the big Swarovski competition one year! The entry was a big display and had to be driven to the contest headquarters. She thinks that she may be responsible for the change in the rules that stipulates that entries have to be "shippable." ;-)
