Well, I've been interested in machinima and model editing in WoW for some time. After posting some work of mine on wow.dev, I was invited to #machinima- and was a bit startled to get such a warm reception.
Also surprising is that it looks like I'll be making my machinima debut in Baron Soosdon's upcoming Unlimited Escapism 00.
Here's a shot from the 10 second clip I whipped up today for it. Rendering it made my laptop sweat blood, but I think it was worth it.
