Artist Vicente Gasco has designed some flower pots based on dendrites, which are an algorithm that creates objects based on things typically found in nature such as coral, veins, tree roots, etc. Each one of these flower pots, due to the algorithm involved is completely unique. You won't find two that end up printing identical. He has made the design available on thingiverse and already others have printed them.
