MyPaint 1.1.0 Release with a bunch of new tools.
MyPaint is especially designed to create images from scratch and it’s not intended to be an image manipulation application (like GIMP), although you can still do many such operations using it. The application features a simple interface, unlimited canvas, extensive brush creation, basic layer support and more and is available for Linux, Windows and Mac OSX.
If you’re into painting and not the heavy graphics that something like the gimp is designed for, this looks nice.
