Shuffle

Slice the image into square pieces and randomly move them around.

Logic: The image is divided according to the Grid Size setting. Next, each piece is moved into a random location on the grid. Upload your own images to experiment.

Note: In my observation, this exercise works very well with photos that we are good at recognizing like people’s faces. Our perception of the face is not disturbed by the manipulation. We can still construct the image of a person even if it’s spliced up and rearranged. Using abstract images can also create interesting results.
