Okay, then...
Basically art class for n00bs. You explained how to draw a box in a way most five year olds know... Most, not all. Though I'm sure a lot of Flash designers never harbored that information in early school years, it isn't so much 3D as perspective. I was hoping for a bit more, honestly, like how to make scenes look 3D as the angle changed. Something like that could have been useful, especially something on how to make something look like it's rotating or something.
