Pacman / Perception Challenge #2

Here is the animation we built in today's FlowCast on Perception. In the cast, we used 2 layers – each a half-circle – to create the chomping effect, by adjusting their anchor points and animating their rotations.

FlowCasts are daily doses of techniques, tricks, and advice on design and animation. We keep things short, light, and focused on a specific idea that will help you become a better animator.

CHALLENGE
Recreate this animation with only a single layer.

HINT
Don't use rotations.

File for this challenge is attached.
