Patently Apple reports on a new patent granted to Apple that describes a 3D display and imaging system. It apparently watches a space in front of the user, enabling her to work with holographic images or virtual representations of her hands that can manipulate virtual objects. It’s hard to see this appearing in a shipping product soon, but Apple’s research labs clearly understand the need to define new forms of virtual interaction that go beyond the keyboard, mouse, and touchscreen. follow link

In Snow Leopard, Option-clicking the Volume icon in the menu bar displays a list of sound input and output devices. Choose one to switch to it; it's much easier than using the Sound preference pane.
