Do you know about Gerhard Richter? the painter? well I made a patch that takes all the images in a folder and does that signature color smudging.
In the file you'll see two fun things:
the replication and stretching of the images, reactive to the number of images in the folder
the animation, a bent use of RGBA delay COMP, used to shift animation axes!
have fun and don't hesitate to ask if anything isn't clear :)
