K-DRON Universe is a unique combination of a map and a globe. It combines projections of hemispheres and of skydomes in polar and lateral configurations. It shows geographic sites located on opposite sides of the traditional globe. It is an excellent visual aid for geography and astronomy. The revolutionary Globe and Celestial Sky projections is based on a 3-D shape called a K-DRON, an eleven-sided spatial form with unique structural, optical and acoustical properties discovered by Janusz Kapusta. Puzzles inspired by K-DRON are also available.
