thingiverse

An object that creates different pixelated shadows depending on the lighting direction. In this case, pacman and a ghost. Any two shadows can be formed by making the appropriate 3D object. Included is the C++ source code for a program to do this. The program takes 2 binary images in PBM format defining the target shadows. The program generates an OpenSCAD model for the appropriate 3D object.
