Art Deco lives on because contemporary architects like to use it in their designs sometimes..

This is fancy entrance for big luxury apartment building ( as I remember either East 37th or East 38th Street) near the East River.

Let me see if anyone has written something on this topic--yes, this from a Fox News article

Generally associated with the flapper style of the 1920s, art deco appeared as a reaction to the excitement of modern developments after World War I and flourished through the '30s and '40s. The art deco period was led by fashion; it was concerned less with functionality and more with creating a modern look that made the most of emerging industrial processes. Rich colors, zigzags and sharply angled and cubistic forms were commonly presented in high-gloss metals, black lacquer, exotic woods, leather and mirrors

. Artistic and glamorous, art deco still influences contemporary geometric designs.

This painted door epitomizes art deco styling. It imitates the use of exotic woods and inlays common during the period; the rich colors and sharp angles were also popular then.

Zebra wood -- as seen in this angular kitchen

-- was one of the rich new woods used during the art deco period, along with Macassar ebony.
Many of the materials and techniques used in this era led to high production costs, so art deco design was used more in public places, such as hotels, restaurants and even the famous luxury ocean liners of the day.

Stepped designs were also very popular, particularly in furniture; they mimicked the architecture of skyscrapers. This modern bathroom

uses art deco inspiration by way of high gloss, the skyscraper design and the use of black. Beautiful!

Black and chrome were thought to reflect new technology, so the color combination was used often in art deco. This powder room displays all the glamour of the period.

Art Deco Borders
Art deco embraced its age of rapid industrialization. Strong zigzags emulated electricity and the sporadic nature of modern jazz. The zigzag and geometric designs of this era have been beautifully replicated in the borders shown here.

Geometric design has definitely enjoyed a revival. The rich colors and design of the flooring here would not have been out of place in the art deco age.
