We have an interesting project that we will soon launch on Kickstarter. It's a book called 'Nature of Form'. The book is a collection of Forms, Colors, and Textures extracted from various elements in nature. It covers 150 elements divided into categories like Fruits, Vegetables, Insects, etc. From these elements, 1454 entities have been derived (432 Forms, 231 Patterns, 791 Colors). The extraction of forms, patterns, and colors was a tedious one but the result was a beautiful book, that has the competence to become any designer's most valuable asset.
