### Rebuild the game!
The blocks have been shuffled! Put them back together so that...
* an egg LED falls from the top of the screen, row by row.
* a basket LED is on the bottom row and can be moved by using the accelerometer `X` data.
* if the egg LED reaches the last row, reset the egg position to the first row.
```shuffle
let basketX = 2
let eggX = 2
let eggY = 0
basic.forever(() => {
led.unplot(basketX, 4)
led.unplot(eggX, eggY)
eggY = eggY + 1
led.plot(eggX, eggY)
basic.pause(300)
let accX = input.acceleration(Dimension.X)
basketX = 2 + Math.min(2, Math.max(-2, accX / 200))
led.plot(basketX, 4)
if (eggY > 4) {
eggY = -1
eggX = Math.random(5)

# glowing pendulum block tutorial
The glowing pendulum changes the screen brightness based on the acceleration measured on the BBC micro:bit.

The blocks have been shuffled! Put them back together so that...
* all LEDs are turned on
* the BBC micro:bit repeats code **forever** that
* reads the acceleration along the ``y`` axis,
* calculate the absolute value of the acceleration
* scales down the acceleration value by a factor of `4`
* uses the scaled value to set the screen **brightness**
