This shot was fairly simple to animate. I finished the animation between students on the weekend. I cut out the former president’s right arm and hand as two separate layers and imported the PNGs into Callipeg. He taps the screen twice in a second. Each tap involved a gradual slow in to the anticipation and then a fast tap on the screen which is done with two frames. I then held the finger on the screen for four frames each time to imply some press time.
You might notice that the depth map is missing the right arm and hand. Animation overrides the need for a depth map. Motion draws peoples attention more than a dimensional scene. Anyway, I could watch him tap that phone in frustration all day long.
