Rendering Tutorials with the Unity Game Engine

I like tutorials, but what I do not like is sitting through a 20 minute video when the explanation can be done in 30 seconds. So instead I created a bit of (very ugly) code to render tutorials in unity instead. I am going for a LEGO instruction set look and feel. But do not think this is a matter of plopping in some blocks and hitting record, loads of minecraft game assets can not be simply imported, and actually require a ton of manual work. Making this video cost the better part of 4 days. Check it out and please give me some feedback, I could realy use it.
