New touch-responsive Liquid Glass interface design "dynamically reacts" when you touch it, according to Apple.

Apple's 2026 operating systems will be unified and see a major visual upgrade called the Liquid Glass design language.

Microsoft has also been using transparency effects in its Windows operating system since it launched Windows Vista in 2007, complete with its own Aero Glass theme. The current version of Windows 11 now uses Microsoft’s Fluent Design language, which increasingly has more of a focus on 3D, colorful, and playful elements.
