The Ghost Effect

You do this by first drawing multiple layers of solid colour(s) on top of each other. Once you think your image is complete move the Fade slider on a little way and off again - very quickly. Repeat this action several times - the image gets progressively more 'ghostly' until it disappears altogether. If you take a photo each time you fade the drawing you can make a stop frame animation of the image disappearing (and if you reverse the order of the photos in the animation the original drawing miraculously reappears!)

Here is a photo from the Chink Chank that shows the 'Ghost' effect.
