http://en.wikipedia.org/wiki/Volume
We need a mathematical computer program that easily subtracts the volume of a sphere from a cylinder to create a weird structure.
We also need to write a computer program that shortens a cylinder as if a strong man is hitting on the top of Cylinder.
Or we need a programme that makes a digital snake dance or divide into some calculated spinning pieces in three dimensional coordinate system simply by changing some parameters.
