This effect was based on the phone’s accelerometer, not real-world environmental lighting, but it’s certainly along the same lines. I miss details like this — I just love that some folks at Apple put time into making a single button look extra cool.
And I just learned a new word: anisotropic.
Update: Apple Pay has some anisotropic effects on iOS 12. If you have an Apple Pay Cash card in the Wallet app, the “card” shimmers like a holographic material as you move the phone around. And when you send cash in iMessage, the dollar amount has a similar effect. These effects are anisotropic, like the button in the iOS 6 Music app, not based on real world lighting. But it’s similar thinking — and shows that this sort of whimsy isn’t entirely extinguished at Apple. My gut feeling is that iOS 13 will bring some of this back, bring back more depth and texture to the UI.
