hey guys, another question for u smart guys out there. My first question is can I move the zsphere chain and pose my zsketch. I would love to be able to pose the sketch. My second question is i see different colors in some peoples sketches. What does this mean? Is it some sort of way to break the zsketch up into sub tools or something. Looking to get advanced in zsketch will take any knowledge u throe my way, links, tuts ect…
1. Yes, you can. 
(Zsketch Palette-Bind)
Have you watched the videos in the ZClassroom?
I think that`the best way to learn more about Zsketch.

There is also a great tutorial in the 3.5 R3 Pixologic folder.
2. I think youre talking about Polygroups. :) Of course you can break the Zsketch up into SubTools (based on the Polygroups) once its a unified skin, but Polygroups have a lot more benefits.
You can learn more about Polygroups here:

I hope that helps.
Thanks for taking the time to relay me all that info. Thanks!!!
