Animators: WaterLock, BoxerLock, GermanSoldierLock and WashLock.
In this collab, participants are only allowed to use images in their animations and drawing in Flash is not allowed. The images can be from anywhere, Google Image, cameras, scanners etc. They then have to import the images into Flash and use them to create their masterpieces.
The huge file size is due to the fact that images or bitmaps consume more space than an ordinary drawing in Flash called "vectors".
