Jovo

JOVO Click 'N Construct is a brand name of a construction toy system invented by Josef Volgger and produced by JOVO International of Helsinge, Denmark. The toy consists of equilateral triangle, square and regular pentagon plastic pieces that click together on their edges, and the edges then act as hinges to allow them to be folded up into three dimensional shapes. The pieces were designed to model regular-faced polyhedra, such as the Platonic solids, Archimedean solids, and Johnson solids.

While JOVO hasn't enjoyed the peak popularity of Zaks, JOVO has outlasted its sister building set. The two are mildly related to Zome and Geomag construction toys, except that they focus on the faces of the polyhedra instead of the edges. JOVO pieces come in six different colors.
