Ok, I see you don't want to over do it. The napalm doesn't have to be real napalm...a can of starting fluid and an electrical spark would work! Still no? Ah well, I'll shelve that idea for later. Don't be jealous when fire-breathing computers become all the rage and you don't have one!
I wasn't suggesting cheesy flames, I was suggesting awesome flames...flames that you can show off to friends and be proud of.
Were you into the whole dragon thing or you just want the beat-up, rustic look that is accociated with that movie?
