This demo uses an animated displacement map filter to make a twirling effect on a photo.
The displacement map image was created from an identity displacementmap svg image that was rasterized to 640x480 pixels and then processed in a normal graphics editor to produce this image. That image is then animated (rotated) by SVG declarative animation (SMIL).
