Experience with Scratch and GameMaker is that it works at the whole of a class down to
grade 3 though I have had smart individuals down to grade 1. But I note that the
cognitive load is higher for these programming tools, they allow multiple objects and are
event driven. The beauty of Turtle Art is its simplicity, only 1 object, the turtle and
no need to get your head around events and their associated actions.
So I agree, lets get something out there, get it road tested and refined and see how low
it will go.

Was thinking, turtle motion arrows should have a picture of the turtle too - to underline
that they are from the turtle's frame, not the child's.
Younger children will have problems with mouse control, particularly with the XO, maybe
the blocks should be bigger?
In slow mode, the blocks could light up as they execute.
Clean could be a pencil eraser or blackboard duster.
Which are better for flow control, smileys or coloured dots?
0-= I prefer 012, if they can't recognise numerals they will have trouble entering them
Where the graphic is not reasonably intuitive, maybe better to retain the text? At least
an adult could read them. Walter is going to do tool tips, that would make my point
irrelevant, graphics on blocks with text tooltips.

Yes, reminds me of Vanuatu, their local language is spoken the village, Bislama is the
national language but the language of instruction may be English or French. I doubt we
would ever see localisation down to the local language level, maybe 1000 speakers.
Final thought. We are not eliminating language, just substituting one symbol set for
another, hopefully more recognisable ones. Language in the wider sense is symbols with
meanings which can be used for communication and as tools to think with. Mathematics is a
language too. Though some blocks could have photorealistic symbols, we are mostly using
abstract symbols like the arrow. (the arrow is based on the bow and arrow but we have all
but forgotten the roots of its symbolism).
Which gives me another thought. Could we have animated images on the blocks. Then we
could photorealistically represent actions like move and flow control.
All just topics for discussion, very happy with what you have done, looking forward to
the installable bundle.
