This series could go on forever - but these are the first four...
It's a series of nano-torials about the rules of perspective - in Blender, but also in any other 3D app. They're very short and quite flashy, and are meant to work a little like magic tricks that are then explained.
PS - I posted a similar story to this a few days ago, but I spotted some problems with the last vid. This is improved.
