Paintbrush 1.0 for Mac OS X
Paintbrush is a Cocoa-based paint program for Mac OS X, similar to Microsoft Paint and the now-defunct MacPaint. The project’s ultimate goal is to recreate the basic functionality of Microsoft Paint, which has been noticeably absent from Mac OS X for years. Paintbrush can open and save to most major image formats, including BMP, PNG, JPEG, and GIF.
Paintbrush is not intended to replace Photoshop or other high-end image editors. Instead, it aims to fill the need for a basic, streamlined editor for those times when you just feel the need to doodle.
