I was zooming in on my #visionOS view to check something and as I got close I was struck but how beautiful the ‘inset' effect on segmented controls is. I’ve faked inset depth for years on iOS with drop shadows and highlight colors...but this is ACTUALLY inset into the window.

Also, I'm not sure I realized that ornaments are actually offset towards the user slightly from the main window which gives it a very subtle bit of texture too.
