Pixen
Pixen is an open-source raster graphics editor created by the Open Sword group. It is designed to create and edit pixel art. It runs on Mac OS X. The latest version is Pixen 3.
Features
Pixen utilizes a basic interface similar to that of Adobe Photoshop. While common tools are included in Pixen, such as the pencil, eraser, and fill tool, Pixen also uses a unique left/right tool system. This system enables the user to assign a different tool to the left and right mouse buttons. This can be used effectively when drawing and erasing. It also features several color palettes, as well as integration with Mac OS X's color options. Like many other bitmap-based applications, Pixen has a layer system that will let you organize parts of an image, name them, or hide them.
