Hi there, surfing I found this: http://www.youtube.com/watch?v=SIg8Omew9Ps and http://sourceforge.jp/projects/gimp-painter/releases/ A japanese guy is working on a fork called GIMP-Painter. I'm testing it and... it really works with tablet pressure ..without X11!. I'm not a programmer so I have no idea how this guy made this, so please programmers, take a look at this, because I think it deserves the effort. I tried the MACPPC 2.6.2 version in my macbook with 2 gigs of ram and leopard and I'm finding it quite interesting. It doesn't detect the tablet in preferences but it just works! (and he's developing some VERY interesting custom tools). Hope u find this useful.
