Nature has always been a powerful source for design inspiration. Jellyfish is one miraculous design by mother nature: it is attractive for its exotic beauty, at the same time it's repulsive due to its poison. My favorite jellyfish images come from BBC's classic Blue Planet (above).
The unique form, color and texture of jellyfish has inspired so many designs, including product, architecture and art.
