Lately, I made a small build.
It is nothing fancy - run of the mill, an IPad 1 screen over a Intuos 2 6x8.
Nowadays, woodguy32 places IPad3 Retina screens over those tablets...
Anyway, for those that want to have an idea of how to do it, and can survive my english and complete lack of cinematic values, here it is: https://www.youtube.com/playlist?list=PLn72apPb2gPsmfs4idbHZX6CONjkRBAl0
9 videos of despair and triumph (sort of - it works).
Most of the issues, errors and c..p applies also to bigger builds.
