This stunning line of geologically-inspired jigsaw puzzles, named Geode, is the creation of Massachusetts-based generative design studio and retailer Nervous System.
As described in their blog:
Geode is a jigsaw puzzle inspired by the formation of agate, a colorful banded stone. Each puzzle is unique, emerging from a computer simulation that creates natural variations in the shape, pieces, and image. Hundreds of lasercut plywood pieces intertwine to form a challenging, maze-like puzzle. Each geode is a slice of an algorithmic rock.
The puzzles are intricately cut in birch plywood, completely unique from each other, and available in two sizes (approx. 180 pieces for $60 and 370 pieces for $95).
