The other day we got this crazy looking contraption in our CSA box. A type of heirloom cauliflower - not an alien birthing pod - the romanesco is also the answer to the question of the secret of life apparently. Here is a nice article on the vector phenomenon of this delectable vegetable. I would suggest serving "level 1" formations to geeks with an interest in mimetic phenomenon, or after the "brownies" at a seminar for architects.
