It's written using XLib from what I remember so maybe we could think about using a more recent set of libraries
such as GTK or QT. Maybe we could develop a Logo Widget that could lead to more varied applications of the
language in the future. After developing the language into a Logo Widget we could sit various interfaces on
top. Or programmers could just create stand alone logo apps. It could work a bit like Wish in TCL/TK.

Marshal designed Screenturtle I think so maybe he can organize a demo for you to look at. What do you think
Marshal? My version's RiscOS so it won't be any use to you.

Making new or less experienced programmers more productive and making programmers able to move to Linux easily.
The learning curve is high. Maybe logo is one answer here if done properly. If we gave it a widget set....

Maybe some good documentation is needed. Documentation done from a teaching perspective instead of just
programmers writing notes about what they've done. The learning curve to program Linux is way too high for your
average Delphi Dabbler to get into for example.

This is my key point. You can't develop a solution without knowing the problem. I think everyone likes to talk
technically and that's good but before we develop anything we need to get into the classroom and decide what it
is we want to achieve. Then write something that enables pupils and teachers to achieve their goals.

It's the act of researching and developing the content which is important and understanding that the
information a child collects can be communicated in a meaningful and structured way for others.

I think most schools have websites in England now that kids publish their work to. The tools they're using are
simple multimedia programs which export HTML and wordpro. which also export to this format.
Maybe if there was something a little more dynamic it could be embedded in a web page as a Java applet. Then
there'd be fewer restrictions to the content. That seems to be the way things are going now anyway with pdf,
flash etc. having readers in Java.
That said, let's get this logo thing sorted. There's no reason that a logo couldn't work as a Java applet as
well. Then kids could publish their programs to the web.
If Seul-edu could publish some kids work then the world could see that kids can use linux and kids could share
what they're doing with one another. Communicating knowledge and ideas is a very important skill and giving
them the chance to communicate their work beyond the boundaries of their class and parents adds another
dimension to it all. I expect kids would be more excited and eager about their work given such possibilities.
