Complete the [magic logo](/lessons/magic-logo/activity) activity and your code will look like this:

```
input.onLogoUp(() => {
basic.plotImage(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
})
```
### Challenge 1
How about when the logo is down? We should display an arrow pointing downward!
### @video td/videos/magic-logo-1-2
```
input.onLogoUp(() => {
basic.plotImage(`
. . # . .
. # # # .
# # # # #
. . # . .
. . # . .
`)
})
input.onLogoDown(() => {
basic.plotImage(`
. . # . .
. . # . .
# # # # #
. # # # .
. . # . .
`) // ***
}) // ***
```
