Wow. That's an interesting solution and one I hadn't even considered. Will KM support several instances of the same clip? Remember, I'm animating a line of penguins (7 of 'em, to be precise), or would each clip have to have the parts of all 7 in place? As you can imagine, 7 penguins will very shortly make onion-skinning a big black blur.

Does KM support anything like a parent-child relationship so that a rotation that I do to say, a flipper on the parent penguin would automatically change the flippers of the others? Man, would that ever cut animation time down (and as they're marching and dancing simultaneously, the synchronization wouldn't look too weird). Yeah, yeah, I know...RTFM, but the FM is big and in Adobe Reader and I'm way too cheap to print the darned thing, at least not until I actually buy the program and commit to it.
