The Null Device
Video has emerged of a demo of Nobi Nobi Boy, Keita ("Katamari Damacy") Takahashi's new game for the PlayStation 3. From looking at it, it seems to involve several elongated characters (consisting of two weighted ends and an elastic middle) running around and wrapping themselves around a flock of various inquisitive barnyard animals (well, those and one koala) in the middle of a featureless grey plane, and occasionally swallowing an animal or two. The commentary doesn't shed much more light on the objectives of the game.
I'm guessing that the somewhat minimalistic surroundings, as well as the lack of any indicators of score or victory conditions, mean that this is a very early prototype, just enough to demonstrate the basic concept, rather than a deliberately-chosen ultra-minimalist aesthetic.
