CrossOver is a a wine-based platform that lets you install Windows software in Linux and OS X machines. According to OMG!Ubuntu, they are giving away the software for free for today only. Just go to this page, enter your name and email and grab the deb (or the relevant package for your distro). Only a few more hours left (coz today means October 31st in Central Daylight Time).
The Ubuntu Geek article on this reports,
Few days back, CodeWeavers started a campaign ‘Flock the Vote’ announcing that they will release CrossOver for free if 100,000 Americans pledge to vote in the 2012 Presidential elections.
CodeWeavers failed to reach stated goal of 100,000 pledges. However, CEO Jeremy White has now decided to give away CrossOver for free anyway.
This CrossOver package usually costs $59.95.
