I've written a new novice-to-intermediate level tutorial on my blog, and am going to try to update ICE-related content as often as work allows. My main goal is to help artists like the many I work with who may have seen ICE and want get into it but who are intimidated by what they perceive as technical/math skills required.
And also as a blog to jot down whatever comes to mind.
ICE needs more content for people first exploring, and a book takes waaay too much time, it so I'm trying to use the blog as a way to help fill some odd knowledge gaps artists may miss while teaching themselves.
So the content may be a bit basic for many here, but regardless feedback is welcome: http://andy.moonbase.net
