This book is a tribute to butterflies and sea slugs, also known as “the butterflies of the sea.” My title comes from this phrase and is written in French as I completed the book during a two-month stay in France. I designed it with an alternative format in mind so it opens as a pull-out accordion book with diamond shaped pages on either side. In it, I hope to convey that nature creates its own art, and the beauty we see in the world improves our perceptions of it.
