THE NEW PREVIEW APP HAS A FUN INTERACTIVE LIQUID GLASS EASTER EGG

Summary from the TLDR Design newsletter

Apple has hidden a playful Liquid Glass easter egg in the new Preview app for iPadOS 26, available in developer beta 6. In the app, users can interact with a fully rendered 3D loupe, mirroring the app icon, which magnifies and distorts the interface beneath it as if it were real glass, though it serves no practical function. This whimsical addition highlights Apple's broader Liquid Glass design overhaul, adding visual flair to system elements across the OS.
