I have such interesting bits lying around my shed and sometimes they just call out to be combined . This is such a case and the whole top part came together happily. I was not sure where it was going and it sat quietly as a group for a month or so. I was making the base for another idea and just picked up the group and it fitted perfectly to the top. In looking as to what I could say with it, I decided that the complex nature of the form was easily overcome by just adding a separate structure on top( the ladders) and my little character has happily dealt with the complex basis of his life…. Ah Serendipity when everything comes together so well.
