Curved geometry in brilliant colour ... the 9 die-cut cards (and 3 solid backer cards) are 13cm square and made from a thick, sturdy cardstock. The Kaleidograph™ can be arranged into over 570 billion designs. Based upon geometry in nature, the Kaleidograph upholds the tradition of the original creative design toys of the Froebel Kindergarten system that are known to have influenced Albert Einstein, Frank Lloyd Wright, Buckminster Fuller, Piet Mondrian, and design education at the Bauhaus. Like the floral forms found in nature, the Kaleidograph Flora is based on interconnected circular radial forms which can be assembled and overlaid into billions of possible patterns. Richly personal and environmentally friendly, the Kaleidograph Flora is a toy for all ages. It fosters creativity, rewards with surprise, and brings out the designer in everyone.
