PHYSICS!!!
This is a simulation of the physics of a piece of silk cloth using the program blender.
Blender is a free to use program that gives you the tools to create objects and sequences that are only limited to what you would like to push yourself to learn.
In this simulation I created a cloth with silk properties and had it collide with five objects. Four cubes and a UV sphere.
Blender can be downloaded on they're web site.
