GLSL rights

[Fractal Grinder]

So I have a couple scenes that use some fo the GLSL shaders you include with Magic, are there any right rescritions or anything I should worry about; or am I free to use them in my live sets and maybe some videos in the future?

[Magic]

The ones that are included with Magic are definitely ok to use, and probably so are the ones in the Expansion Pack (although I haven't looked at every single one), because they are all from GLSL Sandbox, which has a "public domain" policy by default: https://github.com/mrdoob/glsl-sandbox/issues/14.

Shadertoy is different though, because their default policy is non-commercial: https://www.shadertoy.com/terms. So you have to be more careful.
