SCP is a mind-blowing, diverse, high-quality collection of writings and illustrations, all released under the CC-BY-SA free license.
If you never read horror stories written with scientific style -- have a try
[obviously this has nothing to do with OpenSSH Secure CoPy ;)]
Faced with a legal threat through the aggressive use of a RU/EU trademark, the SCP project is raising a legal fund.
I suggest you have a look.
