TANGENT REFRACTION

by Blend Swap
This is a small animation using the material refraction normal tangent.
This gives a siphon aspect. The camera and the circle are exactly on the same axis. If change you one or the other place on X or Y, then move the mapping in the refraction node.https://www.youtube.com/watch?v=ilYINkXfgTs&feature=youtu.be
