This program demonstrates a light source and object of arbitrary geometrycasing a shadow on arbitrary geometry. The program uses OpenGL's feedback, stencil, and boundary tessellation support.
In other word it poses shadow of the different objects selected over the walls. There are two views in which one is normal say our eyes and other the object's eye. It look cool when you choose the object eye to view. Keeping the lights on/off make the things more delicate. There are many other things that is included in this with vast amount of understanding to implement those.

Those who want to works it on the Linux or Unix can compiles the code as below :
cc -o shadowfun shadowfun.c -lglut -lGLU -lGL -lXmu -lXext -lX11 -lm
make sure you have OpenGl libray in the file system, if not get installed it.
