Here's a great video to give you a taste of what last month's PechaKucha Night Vol. 4 in Newcastle, Australia was like, part of the Design+ event.

When you hear the word "concrete" you don't typically think free-flowing fluid or organic structures.

...It's likely you might think of bunkers, gray urbanity, and bleak high-rise structures. However, in "Textile-Reinforced Concrete: Material of the Future" from PKN Maastricht Vol. 20Kevin Pidun of Lehrstuhl für Plastik shows us that textile-reinforced concrete opens a new universe of surprising uses and forms for this gray material. 

Could you live in a different person's home every week?

Ad man Kevin Lynch chose an unusual way to live for a year in Hong Kong. Rather than settling down in one living space, he decided to get to know the city by staying exclusively in AirBnB accommodations.

In "Yearbnb: spending a year in Airbnb apartments throughout Hong Kong" from PKN Hong Kong Vol.  19, nearly halfway through his year-long journey, he shares some of the most entertaining snippets of his experiences.

The "City Focus" this week goes to Shenzhen, a city that celebrates its 20th PechaKucha Night this coming Saturday (September 6). Shenzhen already boasts an impressive presentation archive, comprised of presentations in both English and Chinese.

Chicago's PechaKucha Night Vol. 31 is just over a week away (on Tuesday, September 9), and here's the poster -- designed by Matthew Hoffman -- to prove it.

How can Hawaii become the model agricultural society for the world?

Josh Lanthier-Welch gives a great crash-course on the agricultural history of the Hawaiian islands. The islands went from feeding being self-sufficient to entirely reliant on imports.

In "Beyond Eating Local: Using History as a Guide to a New Food Security" from PKN Honolulu Vol. 18, Josh shows us how the Hawaiians can once again utilise their lush volcanic farmland to return themselves to a sustainable, self-sufficient agricultural society.

"I go to art shows and I lick the paintings."

Educator-turned-artist Jamie Smith confesses to have been unaware Abu Dhabi was a real location until she decided to move there.

This was only the beginning of her journey to become an artist, and in "Writing on the Wall" from PKN Richmond, BC Vol. 5 she shows us how she created a way for individuals to post their anonymous confessions which she could then use as inspiration for her paintings.

"Lazy, that is the first word that comes to my mind when it comes to the creative type."

Laziness means creativity to illustrator/writer/fashion stylist Jodi Sam, as she says it's the hours of daydreaming that allow us to produce our best work. In "From Daydreams to Ink and Pixels" from PKN Tokyo Vol. 116, she speaks about her illustration process, from ink on paper to capturing her work on the computer, to working with clients.

The statistics are overwhelming: 27 million men, women, and children are held in slavery across the world.

Amy Heague's daughter was about the same age as many of the children she came across being held as slaves in Cambodia.

In "27 Million" from PKN Forster Vol. 2, she discusses the reasons why Cambodia became notorious for human trafficking, and the actions she has taken to combat and drive out these horrific injustices. Amy encourages us to find the fire within ourselves to ruthlessly stamp out these practices any way we can.

Are you willing to be caught in the middle of making something you care about? (even if it's awful?)

Matt Candler discusses what he does for fun: building electric motorcycles. In "I Suck, I Fail, I'm Alive" from PKN New Orleans Vol. 13 he speaks about justifying his hobby to his wife and loved ones, learning to love the process of failing 20 times, and the inexplicable pleasure of finally getting it right.
