This short animation loop was done using watercolour pastels, lead pencil and watercolour pencils. It was just an experimental animation using traditional media. For some reason the GIF is all slow and stunted.
And the quality is horrible, but you get the general idea.
(The .AVI works much better.)
If the animation doesn't load, click the 'download' button.
EDIT: I've uploaded a newer version finally. It does an annoying flicker at the end of the cycle (On my computer anyway.) but it's of better quality than the first one.
