For me the sphere is the most beautiful geometric solid, and it has challenged me to open it, breaking it, changing it, enriching and lightening it. I started with monolithic spheres. I like that figure and I admire it because once I heard a definition from a physicist who said that it is the geometric solid that uses the lowest amount of energy of all, I said to myself: Of course!
It is almost perfect, no matter how you look at it. It fascinates me...
