How to distort final rendered image around a spherical region?
I need to distort my final rendered image around a spherical region, so that it looks like everything is being pulled into that region (something like a black hole, as seen in the animation below, taken from wikipedia).
I think I need some post-processing effects to achive this, but I don't know how I can specify which region of the image to distort, as the sphere will be moving around the scene. Any help would be appreciated :D

Looks pretty lame when you have to answer your own question, but here it is anyway:
grab the detonator package from the resources section, and assign the provided "HeatDistort" shader to a billboard. Then use any given normal map texture and you should be on your way.
Well thanks for answering it, because it sure helped me out. I've answered my own question on these forums too :)
