Don’t forget to check the APPS section. I’m always on a look out for free and open source apps to help get things done for visual artists. Obviously, apps such as Guitar and Piano won’t be listed since that isn’t something visual artists use regularly.
It’ll take a while before I really sit down to do any serious 3d studies or works because there are a lot to organize and sort through. Speaking of organizing and backing up, two great softwares have helped me greatly: XnConvert and HandBrake. Both of these apps allow you to batch convert (images and videos respectively). I have turned 73GB into 15GB!
