Believe it or not but it all started from this:

- Peter's challenge
A simple photo that Peter sent me as a challenge without further instructions
By the way, you can also admire Peter's great achievement with this giant build made of Geomag Kids rods (which are longer, heavier and thus proportionally weaker than short rods). Just Bravo!
It took a little time and a lot of observation to figure out how to go about it and where to start. Once I managed to discern the core module and understand how it was made up, I was good to go.
I Got there:
1350 rods and
415 spheres at this stage (out of the 1800 rods and 540 spheres needed to complete the full dodecahedron)

- Dodecahedron almost finished. Only 5 modules missing out of the 20

- Looks like some kind of plasma cannon from this angle!
I was well launched to go to the end but by manipulating the construction I had the idea to explore other possibilities first ...
