Martin, you will need a Render-In-Image patch to render the full screen into a texture. You cache the resulting image in an Accumulator patch. which then goes back into the original Render In Image patch as a new Image input. This image from the last render cycle you render first in the Render In Image patch but with a little shift to the left (dont forget the clear patch on level 1 in the Render In Image patch!). Then you render the transparent image on top of it while give it a spin with the “Rotation Z” parameter. If you put a Core image blur effect on the Accumulator patch, this will give you some extra fuzziness on the trail.
I hope this give you some hints where to start. best, Achim Breidenbach Boinx Software Ltd. PS: The banner of the Facebook page will be exchanged each month by a “I like”-competition.
