Depending on what you want your users to be able to manipulate, you 
may well find that separate Morphs make more sense. If you just want 
to draw something on a big background, you can subclass PasteUpMorph 
and override its drawOn: method (and make a new Project subclass that 
uses one of these). Look at the implementors of drawOn:.

Form isn't, itself, a UI object. It's just a representation of some 
bitmap that can be drawn (it does no user interaction). There is 
ImageMorph, which is a Morph with its own Form. These may make more 
sense to use in your UI. You can receive and respond to user input 
events (mouse, keyboard), you can implement animation or other 
periodic behavior, and you can re-position the image within the 
world.

You can make one from a Form easily:

myImageMorph := someForm asMorph.

Nah, there'll be lots of good ideas here.
