While going my grandma house to bai nian, i noticed something interesting.
On the north-west line(purple) in the tunnel, there is actually TV. Yeah you heard it right, TV. How is it possible to have TV in the tunnel an yet you are able to watch it even though the train is moving :o!

Then i wondered if its like parts of the screen is showing different parts at different places.

But after finding on yahoo search.(internet is so resourceful nowadays)

its like this

(the arrows are to show the way the pictures are moving, along with the train so that the same picture 'seems' to remain at the same position)

Well, if you understand then you understand and if you dont then you dont. Duh?!

How cool the technology has become.
