I wonder why I didn't think of announcing this here, since I know about it since over 12 hours and it's already Wednesday in Europe by now...
The guys over at CodeWeavers are giving away their
CrossOver products CrossOver Mac, CrossOver Linux, CrossOver Games Mac, and CrossOver Games Linux, a fork of WINE, for free today, apparently over losing a bet that GW Bush wouldn't be keeping a single one of the five goals that he announced. Apparently petrol IS cheaper by now.
So, you can download the software for free from
http://down.codeweavers.com/ for probably a few hours more and apply for a registration key there, too. The site is pretty minimalistic now after the servers went to their knees due to the resulting hits on the website - watch the video.
Hope that helps somebody who has to or wants to run Windows programs or play a game or so.
