CADO 
Creativity Aided Design Objects, are luxury playbricks featuring different colors, textures, and shapes, and are made of diverse materials such as wood, aluminium, lead, glass, but also felt, and a variety of stones and stonelike substances such as marble and concrete. Originally designed to serve as visual aids for architects wishing to demonstrate material and material combination possibilities to their clients, CADO has evolved into something new over time, though they might as well be used according to their initial purpose. The sets invite to indulge in visual and haptic experience and stimulate playfulness and creative expression in those who hold them in their hands. Various sets exist, from basic to more fancy designs, also varying in price and volume.
