Vortex

The Vortex image effect distorts the rendered image within a circular region. Pixels in the image are displaced around a central circular area by a specified angle; the amount of displacement reduces with distance from the centre, diminishing to zero at the circle’s edge. Vortex is similar to another image effect called Twirl, although Twirl distorts the image around a point rather than a circle.

As with the other image effects, you must have the Standard Assets Effects package installed before it becomes available.
