This reminded me of a glass artist named Josh Simpson who is known for his glass spheres he calls “planets” that have amazingly complex scenes in them. For over two decades he’s had what he calls the “Infinity Project” where he encourages people to hide them out in the open where folks are unlikely to find one. If you submit a proposal to him that he likes then he’ll send you two of his smaller planets, one for you to hide and one to keep for yourself.
