Movie S2.

How to grow a face from a flat sheet. Movie shows an example of a complex animal shape.In each case, once the growth patterns are determined by solving the inverse problem, we calculate a sequence of elastic equilibria that interpolate between thefeatureless sheet (the reference state) and the final complex shape.
