From the developer:
iPaint is a painting application for Mac OS X. It is based off of a former painting application called Paintbrush. Paintbrush hasn't been updated for almost 1 year and it was time to do something. Paint Brush is open source and full credits are still given in iPaint. You will see dramatic changes in iPaint in iPaint 2.0. I am working hard on bringing a new evolution of painting to Mac.
