http://www.aros.orgThe Amiga Research Operating System project is an reimplementation of the AmigaOS's functions and libraries on a variety of platforms. It's a free, opensource project. Most people's interest in it is that it allows you to run an Amiga-like OS natively on commonly available Intel/AMD PC hardware.
They're some way from completion, but they've come a long way. As far as I know the proceeds from such sales and donations go towards the cash bounties which are awarded to programmers who finish set tasks - at the moment there's a bounty on a TCP/IP stack and a native GCC compiler for AROS.
(Info on the bounties here)Bugger, someone beat me while I was waffling ;-)
