## In this lesson

### Now playing (0:09)

Here's a music app's Now Playing screen. Glass controls float over the cover art. See the light on the rim? It comes from the top left.

### Light that travels (0:19)

Let's send that light round the edge. Click the controls. In the rail, click more, then the marker beside Light angle, for a key here. Press dollar, for the end. Click the value, type three hundred and fifteen, and press return. Once round, every loop.

### A press (0:37)

Now a press, lit from under your finger. Press zero, then Shift-L six times, to two seconds. Click the marker beside Press. Three more, and type eighty. Three more, and zero.

### Watch the light (0:52)

Press escape twice, then zero, and space. The light travels round the rim. And at two seconds, it presses, glowing out from the middle, then lets go.
