Jukebox is a coin sorting puzzle. Insert the red and green coins such that all red coins end up left and the green coins right.

Connectivity is the world's first 3D-printed outside puzzle sculpture. The object is to get the five copper-colored rings through the maze to the pole on top. Connectivity was built for the occasion of the opening of the TNO headquarters in Delft, August 2005.


In 2003, Wim Zwaan of the Netherlands made a couple of big keymazes
