A fractal has been defined as "a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole." There is no better example in our produce aisle right now than this baby Organic Romanesco Cauliflower from Lancaster Farm Fresh Coop in Pennsylvania.
*NOTE*
Coop member Marc points out that it more closely resembles a Calabi-Yau manifold. For those of you unfamiliar, extra dimensions of spacetime are sometimes conjectured to take the form of a 6-dimensional Calabi-Yau manifold.
