I’m starting to think that you have gotten a totally wrong idea about this stuff..
man.. you should just take some free time from this tutorial, rent buy or find yourself a nice copy of Waking Life (you can get that on amazon if you’re not lucky finding it anywhere else), have yourself something to eat and drink and watch the movie…
I’m quite sure that after seeing that movie you’ll understand that tut better. And probably won’t ask that question again 😀
Hope it helps you a little
