Whoosh
Whoosh is a full-featured tube/tunnel/vortex animation system.

Motion The type of distortion created by moving the center point. Modes are: Concentric, Warped, Axial Warp, and Flat.
Render Choose to render the effect or a depth map for the effect.
Depth Map Scatter When rendering a depth map, use scatter to reduce banding in the depth gradient.
Center The center point of the vortex.
Movement This is the main control to animate. For looping animations, it repeats at each full revolution.
Angle Rotate the image around the vortex.
Spiral Twist the vortex
Spiral Depth Controls the perspective distribution of the spiral.
Field of View The field of view for the Whoosh vortex. Simulates Wide/Telephoto effect.
Scaling Choose between uniform and non-uniform scaling.
Scale x Stretch the vortex horizontally
Scale y Stretch the vortex vertically
X Tiles The number of times to tile the source layer horizontally inside the vortex
Y Tiles The number of times to tile the source layer vertically inside the vortex
Mirror Horizontal Mirror the tiles horizontally (works best with an even number of tiles)
Mirror Vertical Mirror the tiles vertically (works best with an even number of tiles)
Stagger Rotates alternating tile rings along the z axis. This will produce visible lines with full frames, so it is best used with layers that are surrounded by transparency.
Post Roll Rotates the entire world after angle, spiral, & scaling have been applied.
Offset Offsets the entire world
Alpha Fade Fade out at the center of the vortex.
Morph to Source Morph the vortex back to the source material. For best results, make X Tiles an even number and Mirror Horizontal.
Super Sample Off, High, or Extreme. Higher quality, but slower rendering.
