Can't wait to see your film...I suggest using the free models hash provides, unless you don't want to feel like your "cheating", even though you're not
I bet if you added music to the sequence and the spider would jump down after a couple of seconds that would be awesome. The music would give a sudden "horror note" that's really loud when the spider comes down
I know this is really old...but you should continue the animation by waiting a couple of seconds and then it suddenly jumps up right in front of the camera..that would be startling
