The heptagon hexahedron unit is different from its mirror image. Both are necessary in this build. On top of the castle there is a Rubik's dodecahedron, the Dutch flag is hanging out. On the build with the Rubik's cubes and varieties (7 cubes in total) there are 3 cheap imitations made in China that I bought in a train in India for about half a euro a piece. In the center there is the original Rubik's cube, there are also 2 varieties that are briefly demonstrated in the video and finally a special issue for the 18 October 2009 gathering in Eindhoven from the Dutch Cube Club. Professor Erno Rubik gave a talk there and signed the cube for me.
