    let top = document.documentElement.scrollTop,
    delta = lastPos - top
    lastPos = top
    frames.forEach(function(n, i) {
    zVals.push((i * zSpacing) + zSpacing)
    zVals[i] += delta * -6
    let frame = frames[i],
    transform = `translateZ(${zVals[i]}px)`
    opacity = zVals[i] < Math.abs(zSpacing) / 1.9 ? 1 : 0
