Is liquid glass a real material?

Liquid Glass, as presented by Apple at WWDC, is not a real material in the physical sense but rather a digital metamaterial designed for Apple's software ecosystem. It introduces a flexible, dynamic layer to apps and system experiences, enhancing the visual and interactive aspects of Apple's user interfaces. Liquid Glass is designed to mimic certain optical qualities of real glass, such as translucency and light refraction, but it is fundamentally a digital construct used to create a more immersive and fluid user experience across Apple's platforms.

For more details, you can refer to the session Meet Liquid Glass (00:00:00) which provides an introduction to this new digital material.
