This standalone 3D puzzle is an intricate and dazzling balancing act with 38 colorful shapes that combine to form an exotic, abstract tree-plus countless bonus configurations-designed by renowned illustrator Bob Staake. Alexander Calder meets Dr. Seuss with this brilliant puzzle that offers a unique building experience perfect for any puzzler or modern art enthusiast. The thirty-eight brightly colored die-cut pieces (called pARTz) fit together to form an astonishing standing sculptural art piece. You can also build countless simpler sculptures using fewer pARTz. One side of the 18x24-inch poster enclosed with the puzzle shows a dinosaur, a giraffe, a bird, and a plane as examples. The other side provides step-by-step instructions for building the Tree. This is an eye- and hand-engaging activity that will provide hundreds of hours of creative fun for puzzle lovers, art lovers, and tinkerers of all ages.
