Free mind-mapping software

The ComputerActive "Ultimate Guide to Free Computing" Jan 2010 (£5.99, but why don't several people buy it between them?) has a CD of full software including MindGenius Home 2, which is a perfectly competent mind-mapping package. It's also got useful guides in the mag to OpenOffice etc. as well as cloud computing tools.

You can download free time-limited trials here, but the magazine version is an unrestricted version of an earlier release.
