Geode Puzzle Jessica Rosenkrantz and Jesse Louis-Rosenberg

Hard Rock Beautiful—and fiendishly difficult—these cutting-edge geode puzzles seduce the eyes while challenging the brain. And like real agate, each of these designs (pink, blue, or multi-colored) has a distinct shape, color, and pattern. The way they’re made is inspired by how a geode’s crystalline structure is created in nature: a special simulation program develops an image by layering color that radiates from the puzzle’s edge; an algorithm generates the puzzle piece patterns; and a computer-guided laser cutter shapes the pieces from birch plywood. We apologize in advance for bending your mind. Made in New York. For an extra challenge, check out Jessica and Jesse’s nebula-inspired Infinite Galaxy Puzzle. Due to the nature of this item, each is unique and will vary.
