## 1. In reference to an animation, what is an "interval"?
<br/>
## 2. What is the interval of the animation?
```
basic.showAnimation(`
. . . . .
. . # . .
. # # # .
. . # . .
. . . . .
`, 400)
```
<br/>
## 3. How can we make this animation never stop displaying on the BBC micro:bit?

## 4. Write the code to create a forever loop that shows an animation of these images. Change the interval from 400 to 800 to make the animation go twice as slow!
