I went to watch a Northern Lights inspired art show by artist Dan Archer called Borealis. It was at the West Kowloon Cultural District, where it lit up the sky with fog machines and blue and green lights shining onto the fog, giving off the impression of the Northern Lights. It was only there for a short time, and has been in many other cities throughout the world as well. I really enjoyed it, as I never thought it would be possible to see the "Northern Lights" from a place as far south as HK.
