I played around with a BeOS demo CD at uni, now I'm downloading a vmware appliance of the open-source version that's risen from the ashes of BeOS
Haiku site: hxxp://haiku-os.org/
VMware appliance: hxxp://www.vmware.com/vmtn/appliances/directory/627
It's still a long way off being a fully featured 'homage' to developer release 5 of BeOS, but should be enough to play with
