[AS2] Animation maker

[Itisasecret]

I'm trying to make an animation maker, no need for ability to save the results or anything, but just so the user could make a simple animation via .swf.

At the moment I've got a simple sketchpad where you draw (simple lineTo) in a movieclip (created via AS), and I've got multiple movieclips ("MovieClip1", "MovieClip2", etc.) in different frames with a button that makes it go to next frame.
So I'm wondering if it's possible to store the lines in AS-created movieclips somehow (without serverside stuff), and then retrieve them in separate frames in a 'holder'.

It so far: http://www.swfcabin.com/open/1253977262

Also, you can still draw in the 'animation', even if the drawingscripts are in the previous frames o_O?
