Remix is a core concept, and essentially an inspiration for the whole Creative Commons concept. The idea is that as discourse becomes digital, it becomes quickly and easily interchangeable. From this elasticity comes the idea (possibility?) of people showing their creativity in remixing songs themselves, or splicing different discourses together to create something new. Think of it as making collages, only, collages with moving parts (film, music, animation, etc.) Therein lies the rub: does slicing together existing digital discourse constitute originality, or is it taking other people’s stuff?
The creative commons has stuff on remix here (with examples), and Uwe Hermann has some good “practical examples” here…
