This is a fantastic, intelligent wedding of word and image. It's like a genuine synthesthetic experience, like the animator wanted us to have a cogent, dependable hallucination of Chomsky's brilliant, eloquent statements. From time to time I would sort of "forget" whether I was hearing Chomsky or seeing what he was saying; they sometimes switched places... or (perhaps more accurately) truly merged in my mind, like finally having the image of one of those 3D "art" images pop out at you when your eyes finally settle into the correct parallax and focus mix. I found that when I was relaxed and letting the flow of ideation wash over me, my experience was "of a piece"; almost psychedelically.
What can I say? It's just a lovely way to mainline a genius' thinking; the filmmaker succeeds in his quest to enhance and tease out the intuitive aspects to technical/scientific thinking; and that's downright inspirational!
Check it out.
--------Addendum
Just want to add one more point. As much as I find Chomsky's politics to be vital and morally attuned, it STILL strikes me as a great artistic decision on the part of Gondry to 1) minimize the politics, 2) put them off 'til (largely) the end, and 3) subsume them to the task of conveying warmth (not urgency). You get a measured, requisite dose of Chomsky's politics, *without* the overwhelming sense one often gets with Chomsky that, up against so much troglodytic inertia, the task truly daunts. Bravo.
