Can be browse in the smart phone and pushed it.
(Like the "Scroll View" function in NGUI ! Is there any better tutorial?)

Click on the small box columns of any image or text,
it will go to the next scene,
and show a interface like Unity3D Asset Store.

Will appear on the screen right and below the bar at the bottom and right of the picture like the Unity3D Asset Store.
And have a introduced long text on the left.(How to make a small text columns can push?)
Click on the small image to enlarge picture after column will display the screen on the right,
There is also a button next to the field in the picture,
Introductory videos can be displayed full screen.
(Or any other mode of operation)
