Automatic photo mosaic effect generated from a movie brush. This was done using a PASeq with 4 paint synthesizer steps. The same movie brush is used for all 4 paint steps, the brush size is cut by 50% each time and after the first pass i tuned on the Texture Range control in the path start control panel and boosted the min texture for each subsequent pass. This causes the smaller images in subsequent passes to only be painted at edges in the source image. I used a Rect Tile path application control panel Mode setting so that the reduce size image passes tiled.
