My wonderful co-workers gave me a suitable send-off which involved these two cakes. They've got big sea urchins and little sea anemones; the one on the left has a whole coral reef background with "sand" around the base of the cake. Is that cool or what? It's one of the prettiest cakes I've ever seen! My co-worker simply gave the cake decorator a picture of strongylocentrotus purpuratus and the explanation that it was for a lab that works on sea urchins, and this is what the woman came up with. Anemones are usually larger than urchins and not the other way round, but I'm not complaining. :) Note also the candle shaped like a sea urchin skeleton.
There was good champagne, and as is tradition in our lab when someone leaves, someone popped the cork into the ceiling and then circled and labeled the dent that it made. (You can hardly see the dent in the photo because my camera flash erased the shadows, but trust me, it's there.) So I've made my mark on the place!
