It's an age old question. We've all pondered it. We've all come up with our answers, and maybe, they're all right. To me, art is broad. It does not have tight restraints or rules. It is wide open and all-encompassing. That's why I love it and fear it all the same.
What, then, when someone, presumably "in" the art world, tells you that your art isn't acceptable merely because of it's format? I'll tell you what. Fuck you is what.
Art doesn't need the constraints of a frame - a frame of reference, maybe... but not a frame.
