Goal: Take apart and put together
This puzzle is a product of our collaboration with my puzzle friend Dmitry Pevnitsky. In all conscience I should say that main contribution was done by Dmintry. Actually you may assess it your self. I just created initial idea Ц puzzle Spiral, but Dmitry saw that it may be transformed in to a treble clef what finally was done. You can see result of it.
But technologically we had to solve quite difficult puzzle to cast this puzzle. It took us almost two years.
