Interesting concept, if I am deciphering your posts correctly...

Not sure if English is your first language, and possibly your thoughts on this are not translating well.

From what I think I understand, you would like an interactive tutorial that is user participated, script driven (where script waits for user input/completion of task, then moves onto next part in tut). Does this sound about right what you are looking for?

If yes; No, I haven't seen such a scripted tutorial for Blender yet (although, DAZ Studio has a scripted user driven tutorial for rendering/learning their software).

I believe it could be done (not by me, though. My coding skills aren't strong enough for what would be needed), and I have no idea what it might cost (or time involved). You might get lucky, and some coder might see this as a viable Market Place product, or code one in spare time as volunteer work/freebie, as you are suggesting.

Definitely interesting concept. Good luck, I hope someone helps you with your vision.
