What is the city of the future? What will it look like? How will it come to be?

This weekend, from Taipei to Melbourne to Mexico City, over 100 local organizers will offer their answers at TEDx events in honor of TEDCity2.0, a day-long TED event to celebrate urban innovation.

TED challenged organizers to remix the official TEDCity2.0 posters
(made by design firm Kiss Me I’m Polish) to give them some local flavor — with really impressive results.  

Below, some of our favorites — including a design from TEDxStormont in Belfast, Northern Ireland — whose team cited Seamus Heaney’s poem, “The Cure at Troy,” as inspiration, a poem signaling new hope for Belfast after long political trauma. Eva Grosman, TEDxStormont’s organizer, sent this excerpt:

“History says, don’t hope
On this side of the grave.
But then, once in a lifetime
The longed-for tidal wave
Of justice can rise up,
And hope and history rhyme.”

1. TEDxChristchurch
: Christchurch, New Zealand

Kaila Colbin, organizer:  “Christchurch is a city best defined by transition, as it seeks to rebuild and reinvent itself following the major earthquakes of 2010 and 2011. Today, the city is littered with shipping containers and broken buildings, but it also boasts seeds of life as creative temporary projects have begun to spring up. A summer events pavilion made entirely of blue shipping pallets or a Cathedral made out of cardboard…these are all signs of the re-emergence of Christchurch as a place to experiment and grow.”

A cathedral from cardboard: TEDxTokyo speaker Shigeru Ban's Cardboard Cathedral in Christchurch, NZ.

Shigeru Ban is an architect who believes architecture is about more than just commission and product, more than aesthetics or pure design — which is why he began using his expertise to build temporary relief housing out of recycled materials, things like paper tubes, beer cartons, and cardboard.

In his talk at TEDxTokyo, "Emergency shelters made from paper,"
Shigeru explains what made him want to build these atypical buildings:

"I was disappointed in my profession,” he says. “We are working for privileged people, for rich people, for government and developers. They have money and power, and those are invisible, so they hire us to visualize their power and money by making monuments of architecture…

I was very disappointed that we are not working for society, even though there are so many people who lost their houses by natural disasters … I thought, even as architects, we can be involved in the reconstruction of temporary housing. We can make it better. So that is why I started working in disaster areas.”

Since his start working with recycled materials in 1986, Shigeru has built multistory housing from shipping containers for victims of the 2011 Tōhoku earthquake and tsunami in Japan; built shelters from local materials in Haiti after the 2010 earthquake; even crafted an elementary school out of paper — the Hualin Paper Elementary School — replacing a school destroyed during the 2008 Sichuan earthquake in China.

Recently, Shigeru rebuilt the Christchurch Cathedral in New Zealand, which was badly damaged in the 2011 Christchurch earthquake. However, his cathedral is a bit different than the original structure, as a good amount of the building materials are paper rather than stone.

Above, images of the newly-opened Christchurch Cardboard Cathedral, which seats 700 and is predicted to last for 50 years while a new,permanent structure is built. Below, Shigeru’s talk, which was featured on TED.com last week:

Note-taking, in style: This weekend at TEDxAuckland in New Zealand, TEDx’ers will be treated to beautiful, one-of-a-kind notebooks to capture all their ideas worth spreading from the event.

Made from recycled paper and vegetable-based inks by New Zealand stationary collective Lovenotes, the notebooks feature original (letterpressed) art by Auckland local Ruby Watson. Ruby was inspired by the TEDxAuckland theme, “Convergence Emergence,” says Lovenotes, as well as the landscape of Auckland — especially the nearby volcanoes.

Check out photos of the notebooks above, and read more about TEDxAuckland at their website.

A discovery that could keep organs alive: John Windsor at TEDxAuckland

For years, causes behind multiple organ failure have been a mystery, often leaving doctors with support, not treatment as their only option. But Dr. John Windsor and his team have made a discovery that may lead to groundbreaking new treatments of organ failure. At TEDxAuckland, he sheds light on this mystery of the human body and takes us through some of the fascinating and elaborate experiments that led to his discoveries. (Filmed at TEDxAuckland)

Each week, we choose four of our favorite talks, highlighting just a few of the enlightening speakers from the TEDx community, and its diverse constellation of ideas worth spreading. Browse all TEDxTalks here »
