It is my favorite animation from Apple. The shapes are blending together seamlessly, they live in a colorful family. Smooth edges become dots, sounds and clicks. Thank you Apple.
From Dandad.org:
"This value is at the core of everything Apple does. Whether it’s a hardware product, a software experience or a service, flawless design has, is, and always will be part of the DNA of the company. Wonderful Tools is a delightful visual journey that celebrates this design principle, through the shapes of Apple’s most iconic products, software experiences and services."
