I recently discovered this lovely animated film called Phantom Limb.

I've been researching for techniques to animate, classically, in Photoshop. I was hoping to find a plugin that allowed sound scrubbing, but to no avail. But this film showed up in my search. I think you'll enjoy it. And afterward, if you liked it and want to find out how it was done, check out this link to an article on Medium about how it was made. It's a great read.
