According to 2009 scifi movie "2012", the world is coming to an End. The movie was based on the ancient Mayan phenomenon, that December 21, 2012 on their calendar is the end of the world.Leaders of big countries secretly began a project to ensure humanity’s survival ( not all of course ), by building enormous Arks ships in a secret mountain at China. Estimates of the dimensions of one Ark state a length of 850 meters, a width of 120-150 meters, and a height of 110 meters.The above Ark ship scifi 3d model based on several photos i found on web.
I hope you enjoy it.
