Farber says (in my recollection, anyway) the European (or classical) art, including film, is culturally assumed to be a monumental slab. It's about that slab, and how it's been shaped, or what's been carved on it. In "termite art" though, your slab has been wormholed countless times, and its meaning is really taking place in the resulting interstices. The actual art of the piece, in other words, and your enjoyment of it, is taking place in the cracks, and the shape of the slab is coincidental and ultimately meaningless.
