hello,
try card dance effect,
expres= sions would be too slow.

Should be easy enough to set up in= 3 steps, below is some pseudo code.

Loop through every = pixel=C2=A0
{
Use the sampleImage expression to sample = the color of the pixel
Convert the RGB to HSV
Use the V= value (luminance) as a multiplier for the position
}
<= br>
This might be a very slow way to do things as it will sample = the image on every frame, maybe there is a more efficient way to do it,

Any ideas or scripts tha= t may do this?
