### Example: rock, paper, scissors ### Example: Flip-flopping arrow
The following example shows one of three images (rock, paper, or scissors) when you shake the micro:bit: If you press button `A`, this program will make a picture of an
arrow and show it on the LED screen. If you press button `B`, the
program will show a picture of the button upside-down.
``` ```blocks
input.onGesture(Gesture.Shake, () => { input.onButtonPressed(Button.A, () => {
let rockpaper = images.createImage(` images.createImage(`

rockpaper.showFrame(Math.random(3)) });
}) input.onButtonPressed(Button.B, () => {
images.createImage(`
