I was in hysterics watching Patches run around and around chasing the ball in this silly toy. This is just some of the images stacked together. Put a total mask on all but the base layer then just used the eraser to paint out the bit I wanted to show. The additional layers are on normal mode, about 79% opacity. Then I ran the whole thing through SEP2 yellow filter 2, set it to overlay mode and reduced opacity to about 30%.
