invisiShimmer

This gizmo creates the effect of an invisible object moving over a background of your choosing.

Inputs:

FG: The object to become invisible.

Matte: An additional matte to use (will defualt to FG alpha channel)

BG: The background to be distorted.

Output:

The node will output the distorted RGBA pass over the BG as default.

This is what I used as a FG test element, A static sphere with a colourwheel and noise used as texture and the noise driving a distortion:

This is the result using a checkerboard on the BG input.

Edge Tab
    Edge Distort On/Off: Turns the edge distortion on and off.

Edge Size Control:
    Size: Control the width of the edge.
    Blur: Blurs the edge selection.

Edge Distort Control:
    Distort Scale: Controls how much the distortion affects the background.
    Blur Amount: Controls how much the background is blurred based on the distortion.

Highlight Controls:
    Highlights: Adds a specular like highlight to the edge, as if the distortion is catching the light
    Highlight Blur: Blurs the highlights.

Core Tab
    Core Distort On/Off: Turns the core distortion on and off.

Noise Controls:
    Show Noise: Show the noise, gives you a better idea of how the images is being distorted.
    Intensity: Controls how much the distortion affects the background.
    Speed: Changes the speed or bubbling of the distortion.
    X/Y Size: Controls the size of the noise, the bigger, the further the distortion moves the background.
    Noise Blur: Softens the noise, creating softer distortion.

Core Distortion Control
    Distort Scale: Controls how much the distortion affects the background.
    Blur Amount: Controls how much the background is blurred based on the distortion.
    Luminance Effect Amount: Controls how the luminance of the FG object Affects the distortion. The Brighter the image the more it get distorted.

Misc Tab
    Premultiply: Choose to premultiply the output by the FG alpha.
    BG Override: Mixes out the distortion against the background. 0 = distorted image over background. 1 = background only.

v1.1 - hopefully fixed version errors
