The video is prefaced with the below frame (I think I glazed over the interface before playing and clicked away to watch the video.) When it was complete, it sent me back here. The triangle is pushed right of the center point of the circle. http://www.apple.com/designed-by-apple/
Now, I realize the height of the left side of the triangle gives it more weight than the right, in which we would shift the triangle to the right to counter this in order to please the eye's desire for balance. In my quick diagram you'll see that I did account for this in the offset "T." I didn't want this to be true, but it was.
And finally, here is the video. Hopefully I didn't shadow the great production of this with my negative acknowledgment. Enjoy.
