I got a very old trial version[1] from 2005. It's awesome. I contacted the developers[2] to see if I could buy a license from them and they said they stopped supporting the Windows version long ago. They gave me a license key to try but it didn't work. Anyone know of a good alternative?[1]: http://download.cnet.com/Soulver/3000-2053_4-10397751.html
