The Big O Show, which was the most popular at the 2012 Yeosu World Expo, is a state-of-the-art show that combines The-O, a 47m high circular sculpture, a sea fountain installed in three rows (120m each) at 10m intervals, 14 beam projectors and 4 lasers. It is a special effects show that creates a fantastic scene with the night sea of ​​Yeosu in the background. Calculating the size of DIO in terms of area, it is about 660㎡, which is more than 1.5 times the size of the world's largest CGV Yeongdeungpo Starium screen. When you watch the sea story using water and fire, light and laser, video and music, video and marine fountains in 3D, you will fall into a dreamlike world. You can truly experience the night view of Yeosu at the ‘Big-O Show’, the largest marine fountain show on earth held on the water after the sun sets.
