[Watch me code this in ~13 minutes](https://www.youtube.com/watch?v=q1vL2_wBSis) . Tested and fully works in WebKit browsers. Works partially in Firefox — positioning and motion is correct, but there’s no rainbow as Firefox doesn’t support `calc()` inside `hsl()`. Completely broken in Edge as there’s no support for `calc()` inside `rotate()` functions or as `animation-delay`.
