The Purpose
Can Alexa visual be more than just reacting people's inquiries? The challenge is, how to leverage the current visual style and use it to differentiate more and more on-going functionalities and states. Also make the visual more stunning and obvious, with better readability in 10-foot experience.
Version 1 - Motion Enhanced
I try to keep it simple and stay within the same design (just increasing width for readability). Using motion to differentiate multiple on-going functionalities and states. 
Version 2 - Wave
Inspired by the traditional voice curve, this voice chrome is developed based off the current Alexa chrome, that has very similar ways reacting to people’s voice commands. The same visual/ motion is also brought into a circular container for other usages.
Version 3 - Particle
To embrace our new particle design language, I built this particle based visual with the same motion behaviors. Because particles are dynamic and don't have a solid shape, it brings a benefit that we can easily morph (fly) particles to other elements. The possibility of transitions could be endless.
