What is DrawBerry?
DrawBerry provides all the same features of commercial applications such as Adobe Illustrator or Inkscape; except in a free, easy to use, lightweight, and powerful application which is also open-source.
With layers, powerful tools, inspectors and workspaces, DrawBerry is a complete and easy-to-use drawing solution. Moreover, CoreImage filters, based on a great Apple technology, offer you new ways to improve your drawing, extending possibilities.
Some even more great features like the magnifying glass or the undo history, will help you to draw more and more accurately.
The project is no longer updated. Last version, 0.8.1, released in 2009, can be still downloaded from the official website.
