It's a stock bryce mat. I scaled down the numbers(up in size) to accommodate the large model scale. The model is a symmetrical lattice made from the shape which I filled in. the plates on top are the shape cut up applied to lattice. the rest is modeled in bryce. The body signature is a lattice also. Photo Impact allows you to control the vertice points on a 2d plane much like in Rhino, allowing a lot of control.
