Kig - Create geometric constructions

Kig is a program for exploring geometric constructions.
It is meant as a better replacement for such free programs as KGeo, KSeg and Dr.Geo and commercial programs like Cabri.
Kig is meant as a useful and powerful utility for high school students and teachers, and as a fun project for me and others. I have learned a lot by working on it, and it's fun to work together with other people on it. I've written much of the Kig code myself, but I've also had a lot of help from other people. Please see the about box for more information.
Anyway, since this is probably what you all came here for, here's a link to the screenshots page.
If you have Kig with Python scripting, you can find the documentation of Kig Pyhon scripting API here.

KTurtle - Program in Logo

KTurtle is an educational programming environment for the KDE Desktop. KTurtle aims to make programming as easy and touchable as possible, and therefore can be used to teach kids the basics of math, geometry and... programming.
The programming language used in KTurtle is loosly based on Logo. KTurtle allows, just like some implementations of Logo, to translate the programming language (the commands, the documentation and the error messages) to native language of the programmer. For more information on translating KTurtle please read the translation how to. Translating the programming language to the native language of the programmer is one of the many ways KTurtle tries to make learning to programming more simple. Other features to help to achieve this goal are: intuitive syntax highlighting, simple error messages, integrated canvas to make drawings on, integrated help function, slow-motion or step execution, and more.
