Twist Image does not have a presence in Second Life.
Mostly because we don't want to look like these people from Draft FCB :)
Truth is, that's not the reason. For those who have been in-world in Second Life, this is the experience until you can can get over the Newbie Hump (I got a good laugh out of this video).
Feel free to find me in Second Life. My name is Mitch Till and I've been in-world for quite some time now (thought I do, occasionally, still bump into walls).
