Tom Delgado takes you on a complete tour of the mansions of Millionaire's Row next to Central Park (aka Fifth Avenue). Millionaire's Row hit its peak in the mid to late 1800's and early 1900's as it went further north. He stops by the Carnegie Mansion, the Frick Mansion, and the Felix Warburg house, among others. Shot by Eric Thirteen.

Fort Tryon Park is a 66 acre park established in 1935 that sits at the Northern tip of Manhattan's Washington Heights neighborhood. In this vintage photograph of the area captured two decades prior, you can see the private C.K. Billings Estate along with its impressive arched pathway structure and massive mansion, sitting where The Met Cloisters sits today.

Here is a Google Street View of the same arched structure, seen from a different angle, as it appears now alongside the Henry Hudson Parkway.

New York based programmer Brian Foo has a fascinating project called Data Driven DJ in which he creates songs and other music experiments derived from data, algorithms and borrowed sounds. Recently, he created a song that uses the 7th Ave Express (a.k.a "2 train") as the metronome, and the neighborhood stops as the intensity of the music based on median income levels at each particular stop.

The goal of this song is to emulate a ride on the New York City Subway's 2 Train through three boroughs: Brooklyn, Manhattan, and The Bronx. At any given time, the quantity and dynamics of the song's instruments correspond to the median household income of that area. For example, as you pass through a wealthier area such as the Financial District, the instruments you hear in the song will increase in quantity, volume, and force.
