arialy-mocap

I wanted to have decorate to bodies through this mocap project. Both figures would be created by cubes. Figure A would be the light source, mostly dark since the inner light would cast a shadow on the visible parts of its cubes, and figure B would be lit only by figure A’s light. I liked the irony of the light source being dark, and the figure without its own light being bright.
