The hashtag officially became part of the Oxford English Dictionary in 2014, and whether you tend to use them or not, they are a pretty unavoidable internet tool that helps users connect related internet content. Maybe you’re hashtagging photos to get featured on a certain account or to poke some fun at yourself (see Justin Timberlake and Jimmy Fallon)? But serious ArchDaily readers have been using “#” to group beautiful photographs of architecture for the better part of a decade. When Instagram announced that it was possible to follow hashtags, die-hard taggers found a way to discover and like new content without actively seeking it out.

"Does this come in black?" is probably the most used phrase during any architect's shopping trip, but nobody really knows why. Search the internet for the reason that architects wear black, you will find that numerous people have written about the subject,—there’s even a book about it! The fact is that other people don't quite understand how many shades of black there actually are like you do. And it's also a common misconception that wearing black is all in the name of convenience, since looking for a specific item in your wardrobes takes 5 times longer when everything looks the same. In short, architects will continue to wear black... at least until something darker comes out.

Federico Babina, the illustrator behind the series of popular architectural interpretations including ARCHITALE and ARCHIPLAY, has just released his latest project: PORTRART, 35 illustrations that tell 35 short stories describing and relating to the individual personalities of 35 artists.

"The shapes, the sculpted and painted geometries of the artists are transformed to draw their faces," explains Babina. Each composition portrays a realistic fantasy in a series of geometric shapes around a central matrix, the portrait. 

Babina continues, "The project attempts to visualize the likeness, personality, and capture the essential features of the protagonist through simple lines, geometries, color, and ink. The idea is to achieve an almost abstract representation without losing the essence of figurative representation."

More than half a century has passed already since Bernanrd Rudofsky exhibited at the New York MOMA a collection of pictures he took during his trips. The exhibition would be named: Architecture Without Architect. This exhibition was shown in more than 80 cities during the following 11 years, and its catalog has become a true referent in what has been called vernacular architecture.

A question arises nowadays: what have architects learned from this famous Architecture Without Architects? But these days there is an even more important question: how much aware are we in the developed countries of the existence of cities without architecture?
