I took a sketch my co-worker drew of a crazy alchemist and animated him in Spine Animator. I really enjoy the software, can't recommend it enough to any fledgling animators.

Very nice :)

I suppose you use the professional version, for the deformation?

I do, We use it for Delver's Drop at Pixelscopic, but our engine doesn't support the deformation tool so I've never really had a chance to mess around with it. I'm anxious to have the opportunity to work with all the spiffy new features.
