Hello there,

I would like to know what free/open source editors do you guys use when animating a simple 2D bone hierarchical skeleton? For some reason I cant find alternatives similar to the Nintendo NitroSystem app for Nintendo DS (dunno if you guys have used it before).

If there is no real alternative, I am going to open source/release my own sprite editor (which is wip) for those of you guys who are interested at saving some time when animating sprites (it's an app specially useful to animate rotations, scalings, and so on)

Even if its preliminary still, its shaping nicely:

Anyways if there is some better alternative I'd like to know if possible, so it saves me some time as well ^__^

Thanks for your time guys
