Nervous System is a generative art studio and one of their most viral projects is their geode jigsaw puzzles. Each puzzle has a unique computer-generated shape and pattern, resulting in the many types of geode puzzles. While each geode turns out unique, the process of computer generation is similar as they code it so that the rock used will grow progressively inwards and fill the chamber. Colors, characteristics, and growth rates are random which results in the unique puzzles. Each of the computer generated images represents a portion of the algorithmic agate.
What I admire most about this project is that its beautiful in its art form, but since its a puzzle it requires logical problem-solving skills. Most puzzles have an outcome that is a rectangular picture, so it is easy to establish the corners and the outside borders. However in this case you would have to work from inside to out, not having any easy puzzle pieces to go off from.
