I have seen many, many short animated films like BLINKITY BLANK. Using very, very simple animation scratched onto the surface of the film, Norman McLaren has created animated shapes and animals that move in perfect synchronization to the musical accompaniment. The music isn't in the form of songs but more playful riffs and sounds as the animation appears, disappears and moves.
The problems for me about this film are that many film makers seemed to have made similar films and it gets pretty tedious after a while. I have already seen and reviewed about a half dozen similar films, though this one is in sync with the music a little better than the others. Still, how much of this does the average person want to see? An interesting experiment but not much more.
