Looks great. (And it will look even better if it (and Morphic) is working with Athens:) ). > > There is now only 1 major bug, and 3 little glitches: > 1.

If you grab the self world morph with the mouse, the morph is not drawn in the morphic WorldMorph anymore, instead the handmorph creates a form and a new canvas for drawing on this form.
