Atomix is a game designed for GNOME in which you have to build molecules, from simple inorganic to extremely complex organic ones, out of isolated atoms.

The first levels can be misleadingly easy, but added complexity always comes with the next level, so that several minutes (or even much more than that) can be spent on getting out of one single level.

A large collection of educational games for small children. It is meant to become some sort of unified interface to integrate more educational games.

language-oriented games now contain vocabulary for too many languages to list them heres. Sounds and voices are also available for a number of languages, check the gcompris-sound packages for your language.

Currently available boards include:

* learning how to use a mouse and keyboard
* learning simple arithmetics
* learning how to read an analog clock
* recognize letters after hearing their names
* reading practice
* small games (memory games, jigsaw puzzles, ...)
* etc.

It is designed so that it is easy to implement new boards to
GCompris.

A number of boards are only available if other packages are
installed, see the Suggests list for more details.

Gobby is an editor which allows to edit text documents and source files collaboratively over a network. All users could work on the file simultaneously without the need to lock it. The parts the various users write are highlighted in different colours and it supports syntax highlighting of various programming and markup languages. A chat window is also included.

Gobby is portable to both Windows and Unix-like platforms and makes use of the Gtk+ toolkit. A dedicated server is available in the sobby package.

This is gpaint (GNU Paint), a small-scale painting program for GNOME, the GNU Desktop Environment. gpaint does not attempt to compete with GIMP, it is just a simple drawing package based on xpaint, along the lines of 'Paintbrush' from a popular non-free operating system.

Currently gpaint has the following features:
* Drawing tools such as ovals, freehand, polygon and text, with
fill or shadow for polygons and closed freehand shapes.
* Cut and paste by selecting irregular regions or polygons.
* Preliminary print support using gnome-print.
* Modern, ease-to-use user interface with tool and color palettes.
* Multiple-image editing in a single instance of the program.
* All the image processing features present in xpaint

Inkscape loads and saves a subset of the SVG (Scalable Vector Graphics)

format, a standard maintained by the WWW consortium.

Inkscape user interface should be familiar from CorelDraw and similar
drawing programs. There are rectangles, ellipses, text items, bitmap
images and freehand curves.
As an added bonus, both vector and bitmap objects can have alpha
transparency and can be arbitrarily transformed.
Inkscape supports multiple opened files and multiple views per file.
Graphics can be printed and exported to png bitmaps.
Some of the import and export features are provided using the packages dia, libwmf-bin, pstoedit, skencil, imagemagick, and perlmagick.
Other extensions use ruby, libxml-xql-perl, python-numpy, and python-lxml
You must have these packages to make full use of all extensions and effects.

KTuberling is a drawing toy for small children with several activites.

* Give the potato a funny face, clothes, and other goodies

* Build a small town, complete with school, zoo, and fire department

* Create a fantastic moonscape with spaceships and aliens

KTuberling can speak the name of each the object in several languages,
to assist in learning basic vocabulary.

Like most of the other vocabulary trainers it uses the "flash card" approach. If you prefer a more general flash card program, please try KWordQuiz

You remember: write the original expression on the front side of the card and the translation on the back. Then look at the cards one after another. If you knew the translation, put it away. If you failed, put it back to try again.

KVocTrain offers the possibility to enter additional properties for your words (e.g. type, usage label, conjugations) and also allows to use them for queries.

There are vocabulary files for KVocTrain which can also be used with KWordQuiz.

KWordQuiz is a general purpose flashcard program, typically used for

vocabulary training.

KWordQuiz can open vocabulary data in various formats, including the kvtml

format used by KDE programs such as Parley, the WQL format used by

WordQuiz for Windows, the xml.gz format used by Pauker, and CSV text.

Kino allows you to record, create, edit, and play movies recorded with DV

Hebrew via freetype. Graphic formats which can be placed in Scribus as images

include PDF, Encapsulated Post Script (eps), TIFF, JPEG, PNG and XPixMap(xpm),

and any bitmap type supported by QT3.

Printing, PDF and SVG creation are done via custom driver libraries and

plug-ins, giving Scribus inventive features: the abilities to include

presentation effects with PDF output, fully scriptable interactive PDF

forms, SVG vector file output. The internal printer drivers fully support

Level 2 and Level 3/PDF 1.4 postscript features including transparency and

font embedding.

Tux Paint is meant to be a simple drawing program for young

children. It is not meant as a general-purpose drawing tool

It IS meant to be fun and easy to use. Sound effects and a

cartoon character help let the user know what's going on, and

keeps them entertained.

Tux Paint is extensible. Brushes and "rubber stamp" shapes can be

dropped in and pulled out. For example, a teacher can drop in a

collection of animal shapes and ask their students to draw an

ecosystem. Each shape can have a sound which is played, and

textual facts which are displayed, when the child selects the shape.

There is no direct access to the computer's underlying intricacies.

The current image is kept when the program quits, and reappears when

it is restarted. Saving images requires no need to create filenames

or use the keyboard. Opening an image is done by selecting it from

a collection of thumbnails.

XaoS allows you to zoom and pan around a fractal in

modes are provided for both the points inside and outside the

selected set. In addition, switching between Mandelbrot and Julia

fractal types is provided.

Other features include autopilot mode, palette changing,

image saving, fractal inversion, filters, and a built in fractal

tutorial.
