Well, this thread may be considered bliss for many people but i think it should be a sticky one!
There's lots of people here tweaking, creating, and also contributting for new software by any means necessary so i thought about a list of open-source software of all kind that could be usefull and also a alternative for hacking, cracking etc.
Blender 3D publisher, is a "very small" 3D program that has lots of functions and it's quite simillar to the expensive 3D programs for sale in the market like 3D Studio Max for example! There's also a great tutorial that makes the program easy to understand! I'm not trying to promote the program, i'm trying to discover Open-Source software around to use in my future projects like the rest of you guys!

If you know, post please!

Thank you
