Abstract objects, towers or even a chair for children: Spinifex Cluster building blocks can be used to create stable architectural masterpieces. Designer Sebastian Kalies was nominated for the German Design Award 2013 for his construction game. The 34 blocks are the same size and lock into each other. Their simple form allows you to build complex constructions, which trains both the cognitive and motor skills of little master builders. Possibly the foundation for a future career in architecture.
