The first development snapshot of OpenOffice.org Aqua has been released into the wild. There is still a lot of work to do, and there has been some progress already since the snapshot was produced.
This snapshot can be downloaded from the OpenOffice.org Aqua Mac Download page
There are a number of things that still don’t work, including printing, exporting to a PDF, copy and paste, drag and drop, and multiple monitors.
There will be some more snapshots in the near future.
