...why is this so cool?
...why do we get excited when there is something creative and full of energy and joy, like this video?
It is because we are made in the image of a creative God who even in our sin we have traits and pointers in how we create and express ourselves that showcase Him.
Don't fool yourself by thinking this is just a cool "routine" or this is for the church of Oprah, God's common grace is being seen in His creation and He receives all glory for this. We may surpress the Truth of this, but there has to be a higher reason why there is something that finds beauty, joy and excitement in displays of creativity. Random chance and molecules cannot explain it away...
