We can see lots of names with an Aa prefix and the street names like:
New York Maze index-Aa
Click any of them like AA Bus, then we can see a map at the top of the screen and a 3D WebGL VR scene of street beneath.
Click the 3D view,hold the left button and move the mouse forward. Actually you are moving the camera forward. Then try to move the camera backward. You will see a bigger view angle of the street.
Or, you can also use the up, down ,left or right keys to move the camera around the street.
Finally, let's keep pressing the down key and see what's happening.
