[Cuis-dev] Turtle Graphics Package

[H. Hirzel]

Hi Mark

I think Benjamin wants to _do_ Turtle graphics.

What about this package

Morphic/Pen.pck.st at master · Cuis-Smalltalk/Morphic · GitHub 
<https://github.com/Cuis-Smalltalk/Morphic/blob/master/Pen.pck.st>

It is in a repository of Ken Dickey. Not sure if you can call that 
'abandoned'.

I do not know how much much maintenance that needs but it looks like 
something Benjamin can check out. If there are issues people on this 
list are surely ready to help.

I also remember having seen Pen implementations in other repositories as 
well.

Regards

Hannes
