Torque feature that could possibly be used.

i know which one you are talking about now
(basically, in the TSE demo, you had a texture on a cube there the texture would grow and shrink dynamically, which is what Yellowbelly suggested to immitate depth perception)
Paralax mapping is almost like bump mapping, but instead of playing with lighting effects to give the impression of a 3 dimesional surface, it distorts the surface\'s texture in such a way(with applies lighting effects im most cases as well) to give a better feel that it is actually a 3 dimensional surface(often times, you could substitue displacement mapping and get almost the same effects, but more so, at hte expense of processing power as displacement mapping actually alters the Geometry of the surface)

hehe, can you tell ive researced this stuff?
