The mise-en-scène to get to Anata Samakhon Throne Hall was superb. The street was sealed of for cars (of normal people), and when you went there, there were gradually less and less light and sound. The food vendors around the area even used wax candles instead of light bulbs. So, the light show was put into the center of the attention - just as if you would've left behind the huzzle and buzzle of Bangkok and left the city.
From a "4D Light and Sound Show" by German artist Philip Geist to celebrate King Bhumibol's 82nd birthday.
