I’ve been playing with this little free animation software and I find it pretty satisfying. It’s a really simple, basic program, but I like the way that it mimics the look of pencil-drawn sketches; I feel like I can draw in a more natural style with Pencil than with Flash. Obviously Flash is a much more complex program and allows for all different sorts of control over the way your images are animated etc. etc., but for its own simpler purposes, I enjoy this program.
