Mindomo is a free mind mapping tool which has been created using Adobe Flash and can run inside your web browser. Because of this it makes it a handy tool for organsing your thoughts wherever you are, as long as you have access to a computer and the internet.

Mindomo has some great features and is in constant development. It has the usual tools you'd expect to find such as selecting lines styles, colours and widths, there is a small image library, a tool to balance your map and the ability to link to website addresses.

To use Mindomo you have to first register an account. The only draw back is the free version has a limit of 5 mind maps per account. Although individual mind maps don't appear to have a limit to the number of nodes.
