For example, the Photo , can only be created by perfectly balancing every sphere as explained in Unimag's "secret". All the spheres must therefore be neutral.
The only exceptions are the 12 sphere which make up the vertexes of the 12 pentagonal based pyramids.
An odd number of bars (5) converge and therefore it is impossible to have one South pole .
for every North pole. If you manage to build this figure, you have become a Unimag specialist!
