A new idea. The cylinder in the middle of this ring will be a sphere. A large sphere in a ring of smaller ones. The first bit goes quite fast as I have been chopping away happily. I know however that things will proceed much more slowly now as the space between the spheres will take time and slow careful work. My recent exploration into positive and negative space makes me wonder about the lumpy crescent shape that will arise here. I am not sure if the big sphere will want to be at the bottom or at the side or even hanging at the top. I shall mull over this and hope for some clarity over the next few days.
