Any good Spinning tutorials?

Hey guys. I have a tool coming out soon which makes use of spinning text. I understand how and what to do but one of my testers is very unfamiliar with this and he just doesnt seem to get it or how powerful it is.

I would love to be able to point him in the direction of a good tutorial so that I can show him the power of this stuff, as you have probably guessed I am no professional teacher and just cannot seem to get it through to him how to use it properly or how to nest them.

Thanks in advance guys. And this is not meant as a discussion about any tool, just asking for a tut on spinning / spintax, cheers.
