The Blender API provides us with the means to define IPOs from scratch, enabling the definition of movements not easily re-created by setting key frames by hand. Thus there is more to IPOs than just driving one IPO by another one.

We will encounter both shape keys and poses later on in this article, but we will start off with looking at how we might define an IPO from scratch.
