Fetal was actually the birthplace of the newborn from my Rebirth sculpture.

They were initially carved in wood and metal, and exhibited as such.

Then, When the vision came in for Rebirth, they were then used as the internal sctructure, which was carved upwards in a myriad of material such as wax, clay, and at one point cockroaches- an ode to the everlasting, everliving, resiliant outcasts.
