You can watch this light show at Formosa Boulevard Station in Kaohsiung. It's a nice addition to the MRT station as it often has amazing light shows, I've seen it and thought the show was pretty neat!
The Dome of Light was created by renowned artist Narcissus Quagliata. The dome is quoted to be "the world's largest public art installation made from individual pieces of colored glass" which I can totally see why! The Dome of Light took nearly four years to complete. The work was overseen personally by Quagliata and shipped from Germany for installation at the station.
The show itself showcases the story of human life in four chronologically arranged themes:
Water: The Womb of Life
Earth: Prosperity and Growth
Light: The Creative Spirit
Fire: Destruction and Rebirth
Definitely an interesting place that you should visit during your travels in Taiwan!
