Or like showing something like, say, Tellytubbies to Roger Ebert? The "complexity" works both ways, surely.

Imagine if somebody had never seen anything before, and they watched a Norman McLaren short experimental film. I don't the name, but I remember one where it was just a pink frame with yellow lines that he'd drawn onto the celluloid directly, and these lines moved and complimented the soundtrack, which was a succession of electronic sounds.

Completely abstract stuff, the meaning and appreciation of it entirely self-contained. It's the kind of stuff people call "artsy fartsy", because they cannot even begin to comprehend something whose meaning does not speak out, but draws in. In fact, it doesn't even draw in; it's just within its own self-contained existence.
