This is the normal traffic map that most folks use: http://www.wsdot.wa.gov/traffic/seattle/<p>And this map adds a third dimension: http://seattletraffic3d.herokuapp.com/<p>:)
Kinda cool, but it bottoms out at 0 degrees of inclination for all Y coordinates in the bottom half of the window, which is a really useless perspective. How about bounding the range of angles, between something like 30 and 90 degrees?
Pretty cool, what did you use to build it? The navigation was a little difficult to grasp, might be more intuitive with a click and drag interface, or something with buttons i.e. google earth.
