Hey that shader is cool
Keep up the good work.
I kinda modified your shader but i couldn't test it. I just added the ventilator's enviromental mapping shader as another pass, but i can't guarantee it'll work cause i'm a newbie to shader programing.

Hope it works. Now i must learn physics, i have a test tommorow
. Good night
