Motionographer points to this cool Barclaycard ad that shows what a city-wide rollercoaster might look like if it were built in New York. This would be a dream come true if it were an actual ride, but obviously, something of this magnitude would never pass. Or if it did, NYC would take decades building it.

Hit up Motionographer for the full credits and a downloadable version of the ad.

Oh, and watch the video below to see how they made the ad. The use of SpyderCam is totally awesome!
