The tile-based eToy system is actually aimed at children, but even I 
use it for small things. It's so easy and so much fun :-)

Smalltalk is the language underlying all this. To use it, you need to 
open a browser. Just start by looking around first.

They are the same. A morph (an object on the screen) can act like a 
turtle - go forward, turn, put the pen down, etc. The turtle idea comes 
from Logo (another programming system), and somehow the name has stuck 
in the code. Normally, we refer to these scribblies as "pen trails".

Use trails in a transparent playfield. on top of your rectangle. I 
wonder if this could be considered a bug, too. I'd expect pen trails to 
come out on top of the painted background.
