Video 7:28 (Video controls are at the bottom of the video. You can stop and reposition the video.)

     First let me show you the wiring language that the business people use.

     Wiring doesn’t do arithmetic or algorithms, but it renders user interfaces, moves objects in and out of collections, and handles user-interface events.

     Application data objects flow from left to right on the wires. "Projectors" are components that render their inputs on the user interface. You will see both the wiring tool (on the left) and the application being built (on the right). You can touch either one at any time.

     I'll show you a common wiring pattern, in which a collection is projected into a list box, and the selected item is available for use in the wiring.
