/*
 * BLINKY LIGHT face
 *
 * The blinky light watch face was designed as a tutorial for making a watch
 * face in Movement, but it actually might be useful to have a blinking light
 * in a pinch.
 *
 * The screen displays the name of the watch face (”BL”), as well as an S at
 * the top right for slow blink or an F for fast blink. The bottom line selects
 * the color: green, red or yellow. You can change the speed of the blinking
 * light by pressing the Alarm button, and change the color with the Light
 * button. A long press on the Alarm button starts the blinking light, and
 * another long press stops it.
 *
 * Note that this will chew through your battery! The green LED uses about
 * 450µA at full brightness, which is 45 times the normal power consumption of
 * the watch. The red LED is an order of magnitude less efficient (4500 µA),
 * and the yellow setting lights both LEDs, which chews through nearly
 * 5 milliamperes. This means that one hour of yellow blinking is likely to
 * eat up between 2 and 3 percent of the battery’s usable life!
 *
 * Still, if you need to signal your location to someone in a dark forest,
 * this watch face could come in handy. Just try to use the green LED as much
 * as you can.
