XMind, the Mind Mapping software based on the Eclipse RC platform has gone Open Source! XMind is definitely one of my favorite pieces of software; though the price has been a bit prohibitive for many people. Now that it is open source, with an optional “Pro” version with some added collaboration features, it should probably get a bigger foothold in the mind mapping echosystem.

If you need a software app that help you structure your thoughts XMind I suggest you try XMind. It is available for download at the XMind website for all major operating systems; Mac OS X, Windows and Linux.
