it's really sad to see project abandoned to themself, 4P aka UberPaint is really unfinished and there's no idea of what happened to him (the creator) since 2002.. will it make the same end of AOCP ? btw the code is there free to be upgraded.. let's see what will happen....
apart from this the other are:
- KolourPaint (a sort of PPaint for KDE) has never started
- Unix Paint is nothing more than the old Win Paint program, no brush selection... I'm really not impressed by the screenshots, apart from the fact is the best I saw here... may be the only to be tried
- XPaint is the most updated, last release is dated 10th of June 2003, not bad... but seems (no screenshots) really basic paint program
- gpaint is really outdated (2000) and has nothing more than Unix Paint or whatever
