Video. Via Drawn!, which says "Some of the stuff is rendered beautifully while other stuff misses the mark and lands somewhere in the uncanny valley," and the commenters over there — jealous animators? — are rather cruel. All I'll say is that the expensive item in the ad is something I held in my hands a few weeks ago and came this close to buying. I'm sure if I had seen the ad, I would have bought it.
The animator, James Jean, has a blog.
