Found a new infinite canvas drawing tool for mac.. i was an avid user of mypaint, an opensource project which provides infinite canvas and is pretty good on windows and linux. On mac you will need to install macports which seems to be a little problematic .. as in i couldnt' get it to work when i tried today so i started looking for a native mac app. I found a bunch of them but the one which is free and is pretty good to use is Mischief. Here is a drawing i made in it, i used wacom bamboo to draw after a while, i used gimp to edit the exported png from mischief. Hope you like it.
