John Green said this quote

What I love about the sculpture is that it makes the bones that we are always walking and playing on manifest, like in a world that so often denies the reality of death and the reality that we are surrounded by and outnumbered by the dead. Here, is a very playful way of acknowledging that and acknowledging that and that always, whenever we play, whenever we live, we are living in both literal and metaphorical ways on the memory and bones of the dead.
