Great work !

Probably a little out of topic but on the same track is toontalk

Toontalk is not open source and free, but cheap and the beta version can be used freely if you give feed back.
With tootalk we get an  interaction when an object is droped on an other. 

This way programing is recording these interactions while training a robot to do things.

Programmation is no more lexical but procedural.

Many kids which have difficulties at school, have problems with langage but have the thinking of action,can do but can not explain with words.

When I discover Squeak , they easily  pass to Squeak and find similarities like:

Book associated to an object with toontalk are the same as wiewer from blue eye with  Squeak.

In this way, I have writen a project for building geometric figures with Etoys, using the interface gadget for the variable of type player to designate objects used as parameter.

This concern not programming but building by doing versus describing.

See the project on the swiki of the french community.


How to start:

Clic on objects in the green area to get a copy.

For instanc get two copies of ellipses(points) then a coy of a straight line.

Click on each yellow square and show a point.
Clic on go to active scripts.

You have built a straight line passing by two points.

Help ballon explain what thing to show for a gadget. Sorry in french. But using red halo menu debug/edit ballon help anybody can change it for any language).

Be carrefull 

Hitting just publish will save the project back on the server. hit alt/dot to abort saving in this case!

The right way:
Stay on publish and choose 'publish on another server' to save the project  in your computer.

Best regards

Sounds very interesting :) I of course searched the PDF for  
"OLPC" (being one of the guys who puts Etoys onto the OLPC machine),  
but it only has a brief mention. I'd be interested in your take on that.

 From my perspective, the hardware is surely there and pretty much  
could account for the "book" in "dynabook". The question is, from  
today's perspective, what software could fulfill the "dyna" part of it?

Maybe you even have some thoughts on the reality of a dynabook in  
your thesis, going to read it asap :)
