I like the Polygon's extensive tile scripting capability, but I am afraid it 
wont be intuitive to young children. Currently, a small Rectangle (or an 
Ellipse) with its pen down offers an easier approach by ticking through the 
following script :

   Rectangle pen color := Rectangle color
   Rectangle pen size  := Recangle width.

Now the child can manipulate the pen directly through halo menu buttons - 
scale, rotate, move and recolor and then use the GrabMorph to create a sketch 
out of the trails. This is much harder than what it needs to be.

BTW, I noticed that objects dropped on the onion skin (or TinyPaint) stamp 
right through them! Abstract layers in a concrete world of Morphs?
