object model to give you a sense of where you live

one of the first recommended reads i encountered in FlashDevelop's community forum, and with all merits, was the display object model.

it gives you a sense of how display works. I needed that when i tried Silverlight, i still need it here.
Think I'm going to stick around, see what this Tibi guy has to say...
