Great I didn't see that :)

I'm not an artist either but if I succeed (one day) to make something
descent I'll let you know.

Ooops, my apologies, I understand "why" now , I don't like the
implications but at least I understand it.

Yes I think it's a strong point of rur-ple, I also like that in xturtle
which give full access to Python.

I don't think Papert is interested at all in Logo as a "language" but only
as a possible vehicule for the maths and exploration concepts behind it (to
produce "hard-fun" "tools to think with"/ microworlds /
differential/kinesthesic approach, etc ). That's why I think it could have a
great future with Python inside the "turtles" concepts.

It was just my opinion but as I said if think the robot approach is very
valid and you're doing a great job.
Now I understand the left turn only but it seems strange for me :
When I was a kid, Japanimation and the Mecha genre invaded France and Italy
and it was a huge hit. At Christmas all boys had cool robot toys. I think if
we saw a robot which has been designed to turn left only but not right we
would have killed and bury him to preserve robots reputation :(
I guess I was spoiled ...

Thanks for your explanations and honesty but I guess you also have more
diplomatic skills on your side of the Atlantic which is not bad. :)
