Nervous System creates jewelry based on the patterns in nature. Their Algal Bloom line is based on the patters found in growing mats of algae. Their dendrite line is based on the shape of coral. And you can also help design your own patterns: 

An interactive algorithm controls the aggregation allowing consumers to participate in the design process.
