This versatile building set combines both art and science with pieces that build 3-D structures that serve not only as décor or architectural models, but also as marble runs in which the activity of the balls is unpredictable.

Designed by a former architect, Q-BA-MAZE (kyoo-ba-maze) is a construction system of interlocking cubes that form pathways for rolling balls. The system uses just three kinds of cubes and is easy to learn, but is also endlessly fascinating because the cubes attach in many different combinations and the action of the balls is so unpredictable. It is part art and part science, and even adults can enjoy it as an interactive desktop sculpture. “We believe in the value of design: product design that inspires creative play for children and adults; packaging design that uses resources efficiently, stands out on the shelf and demonstrates the product in the box; and web design that provides lasting value beyond the box with helpful videos, interactive tools and printer-friendly PDF instructions,” CEO Andrew Comfort told TDmonthly. Launch date: May 1, 2007.
— “We picked up a new toy called Q-Ba-Maze and those have been really, really popular,” Alicia Smith, owner of Juneau’s Imagination Station in Juneau, Alaska, told TDmonthly in May 2008.
