The Xmatrix Quadrus is a quality new, beautiful and mesmerizing three-dimensional ball-in-a-box puzzle. It is unlike any puzzle you have ever seen before, being a cross between game and art-piece. The translucent, pixelated, crystalline layers play with light in a stunningly sculptural and interactive way. Most puzzles of this type are visual mazes. Quadrus is visual as well as mental, in that the path only reveals itself during play. Remember the shape of this invisible path and you can find your way. The puzzle looks and feels elegant and luxurious and is self-contained with no pieces to lose. It has small raised corners to help prevent surface scratching and stop it slipping out of your hand. The handy size makes it easy to hold, easy to stack in-store and easy to transport. The name was developed from the qualities of the product. X (marks the spot, and is the unknown factor), Matrix (cavity in which something is formed, and elements in rows and columns). The unique ambigram logo was developed to fit onto the product and the packaging, so that it always reads correctly and plays on the idea that you have to 'turn it upside-down'. The packaging allows maximum visibility, so the customer can see and try-out the product. The instructions are simple to understand and the overall concept can be developed. An affordable addictive futuristic gift, a collectable coffee-table conversation piece or an artistic object of contemplation?
