CreatureS - or CreatureSystem - is a Linux-based, community developed operating system.  The difference between this Linux operating system and others is that its built for furries.  It will have themes, programs, and more.  And CreatureS is free to download, use, and copy.  You'll never have to pay for a license of CreatureS or worry about paying for support.  Its all free.

Its Free?

Yes, CreatureS and online support for it is completely free. 

Why is it Free?

A better question is why shouldn't it be free.  

Information is power. Computers and their software are tools of information, therefore should be free and available to all. If people do not take up their right to partake in a free and equal exchange of information, they will be enslaved by those who seek to keep that information from them for their own gain, holding it above people, only bringing it within reach for a price, thus keeping the power only in their hands, not in the hands of the people. Knowledge is free. CreatureS is free.

Where can I download it?

As of right now CreatureS is still in the Alpha stage of development and does not have a working iso. When it is released, the CreatureS iso will be avaliable via torrents.
