Thanks Jsmith82 and nice conversion too.
Ironically, in this particular image the successful 3D effect exposes the "trick" of the woman holding up the Tower as she can now be clearly seen to be in the foreground.

It's one of the few examples where 2D is better than 3D for the optical illusion to work.
In preparation for some possible extra interest in my conversion, I've reduced the downloadable COS 3D price even further.
