Intricate natural forms emerge from simple logic. Small change in the logic results in incredible variations. Snowflakes, tree branches, seashells, these are all fascinating natural formation with infinite possibilities.
I created a series of 'airshells', shells that mimic the logic of seashell formation, for Tilandsia, or air plants. You can make your own using my webpage at
A year ago I read The Sixth Extinction (https://en.wikipedia.org/wiki/The_Sixth_Extinction:_An_Unnatural_History). In one chapter called "Dropping Acid", I read how the current acidification of ocean makes calcification of corals and shells difficult, and might cause the extinction of the beautiful creatures. It's painful to imagine the loss, and I feel I need to do something about it. Something that captures the beauty and uniqueness of the shells.
