Public art, surely, can be very cool!

  I don't know if you guys have watched any public movies in the U.S. It was once really popular in China, people from the community gather in a plaza to watch a movie. There is usually a huge screen and a projector, just like a movie theatre but it is entirely in open air. Though we may not enjoy such good picture quality or sound effect as in a cinema, but the atmosphere is really rejoicing. The idea to share enjoyment with others is a key characteristic of Chinese community culture. And public movie is the best media to convey this. However, it disappeared after 2000 when people become more concerned with the quality as a result of Hollywood Movie bombardment.
    Still, though they become rare but the technology advancement gradually make those public movies an art form. It is no longer for entertainment but for higher level of function, just like a sculpture or a monument does. Modern science has enabled people to project pictures onto high-pressure water fountains; the water curtain acts as the screen so the image formed is really impressive. There is a water fountain capable of playing movie in People's Square, Dalian, the city I come from. I once watched it and was immediately attracted by the magnificent effect made from the combination of projections and water curtain. But it has a big disadvantage: it consumes too much water. Therefore, the fountain movie is available only once a year!
    Because this technology is so sophisticated, only a few cities in China can afford the cost of such a water fountain. It has become a symbol of prosperity (though from some aspect a symbol of extravagance). Such a luxurious art-piece add a special feature to the city.

Below is the most astonishing pulic art form I've ever seen: a 3-D stereoscopic projection movie on public building! The video is taken (not sure) on the national day of Ukraine this year. The technology used in this movie is fantastic; it is really incredible to have such stereoscopic images on a wall of a building!
