Finally, a free desktop application that lets you paint/draw. Ever since Appleworks went away I've been looking for a program that would replace their drawing/painting application. Paint Brush is that tool.
PB is very similar to MacPaint or even Tux Paint (minus the Kid Pix type stuff) w/ more options. It's very easy to use and you can even import your own photos and draw over that. It has standard save features such as: png, bmp, jpeg, etc. Also, there is a selection tool, eye dropper, shapes, etc. Anyone familiar w/ paint/draw programs will feel right at home here. While Paint Brush doesn't have all the bells/whistles as say other programs, being that it is 100% free it is definitely worth a look.
Enjoy (and I mean that loosely) my xServ example...
