what the animation things or liquid glass, give me a sample of that

Liquid Glass is a new design material introduced by Apple, which brings a dynamic and fluid layer to apps and system experiences. It is designed to feel responsive, satisfying, and alive, with a gel-like flexibility that communicates its transient and malleable nature. Liquid Glass dynamically morphs and adapts to different contexts and environments, providing a sense of fluidity and immersion in the user interface.

For a sample of how Liquid Glass is used, you can refer to the session Meet Liquid Glass (00:03:47), where it is described as having optical qualities of glass and a fluidity that transforms depending on your content or context. It beautifully refracts light and dynamically reacts to movement, creating a lively experience.

Additionally, in the session Build a UIKit app with the new design (19:15), Liquid Glass is used as an interactive layer that floats above content, providing main controls that users interact with. It is recommended to limit Liquid Glass to the most important elements of your app to maintain the illusion of a single floating layer of glass.

These sessions provide insights into the design principles and practical applications of Liquid Glass in Apple's ecosystem.
