Forest of Stone — Sagrada Família
Inside Gaudí's Sagrada Família, the columns don't just hold up the ceiling — they seem to grow into it, branching upward like a stone canopy over Barcelona. Warm ochres shift into cool grays as the eye climbs from column to vault, and every surface carries a texture our laser can chase into individual pieces. That's exactly the kind of image our cut algorithm loves: dense, rhythmic geometry with just enough irregularity to hide a few surprises. Expect long, branching whimsy pieces that echo the columns themselves, tucked into the vaulting where the light plays tricks. Piece flow follows the architecture's own lines rather than a flat grid, so solvers work outward along the ribs the same way your eye does standing beneath them. Photographed inside the still-unfinished basilica, a building under construction for over a century.
