            . . . . #
            . . . . #
            `)
    } else if (zoombit.isLineDetectedOn(LinePosition.Left1)) {
        basic.showLeds(`
            . . . # .
            . . . # .
            . . . # .
            . . . # .
            . . . # .
            `)
    } else if (zoombit.isLineDetectedOn(LinePosition.Center)) {
        basic.showLeds(`
            . . # . .
            . . # . .
            . . # . .
            . . # . .
            . . # . .
            `)
    } else if (zoombit.isLineDetectedOn(LinePosition.Right1)) {
        basic.showLeds(`
            . # . . .
            . # . . .
            . # . . .
            . # . . .

    } else if (zoombit.isLineDetectedOn(LinePosition.Right2)) {
        basic.showLeds(`
            # . . . .
            # . . . .
            # . . . .
