may be interesting for all pixel artists or who may be searching a free pixel tools:

after a few years nothing changed with source-code of grafx 2 - a free pixel tool with just an old windows and a dos version. But there is hope: A few people have optimize the original source code and released it again as an open source project, now.

So far they managed to clean up the source a lot and build it up on sdl to port it to more platforms. And what I can say: they made it possible: "Grafx 2 97%"is now running nice on linux , windows and even a port for mac os has been released.
So try it out and make your on "image" out of it.

Download links at Pouet with a lot helpful comments:

Visit the open source project Website if you may want to support them or look if there is a newer version in the repository you may want to compile for yourself:

My personal opinion:

For the design and usage of the tool new users may need getting used to it.
As I am a big fan from brilliance (old amiga pixel-tool like Deluxe Paint) which comes with a similar gui and usage I like this tool, all real necessary features are given.

So far a great project - and the people behind it have managed to adjust a lot.
Great - still a way to go for a few features - but I am sure the people will keep updating the tool after the comments I have read from one of the programmers.

A last note on compiling on linux:

make sure you have SDL and SDL_image (along with the dev files)installed if you want to compile the tool.

On Debian/ubuntu you can include them with:
aptitude install libsdl1.2-dev libsdl-image1.2-dev build-essential

and then as usally you can get and compile the source with

svn checkout hxxp://grafx2.googlecode.com/svn/trunk/ grafx2-read-only
(replace the xx of course with tt)and let it then be followed by a:
make

and then you may start it with the ./grafx2

So enjoy !
