PartitionMorpher aims to be a simple yet powerful disk partitioning
tool, based on gtk2.

See http://morphix.sourceforge.net/modules/newbb/viewtopic.php?topic_id=24&forum=3
for an early discussion about this tool.

See http://am.xs4all.nl/phpwiki/index.php/PartitionMorpher for the subproject's wiki page

Make sure you backup all data before using this tool! I'm not kidding (this time), PM is still very much alpha-software!
