How would the twin towers of the World Trade Center have looked from the location in New York City where you are standing now?

A new augmented reality app shows you, by adding the silhouette of the towers to the view of the skyline, as seen through the camera on your iPhone. Then you can take a photo that includes the silhouette.

The app's creator, Brian August, hopes it will trigger memories linked to the iconic buildings before they were destroyed on Sept. 11, 2001.

After all, they are an integral part of his own memories.

"My dad got remarried there. I used to see them from driving into the city with my family when I was a kid. These are all my stories," he told CBC's Spark in an interview that will air Sunday.

"They're the feelings that, essentially, we forgot and were lost because the icon of the towers was missing. And by putting them back in, you kind of prompt people, you cajole them to come forward and share their stories."

In fact, the app, called 110 Stories, asks users to comment on why they took a photo with it.

"For me personally, it's not enough just to have someone take the picture," August said. "I want to have a document of their emotions."

The story of 110 Stories is one of two that aired on Spark on Sunday, the tenth anniversary, describing the use of technology to remember 9/11.

Computers also played a crucial role in designing the 9/11 memorial in New York City. The memorial includes almost three thousand names inscribed in bronze parapets that stream around two reflecting pools.

Architect Michael Arad wanted the names to be arranged in a way that represented their real-life relationships, so that siblings, co-workers, or other victims linked in some way would appear close together. His vision was also to loosely group names by which tower or flight they were on or which company they worked for.

"With almost 3000 victim names and over 1200 of these adjacencies, it's just something that I would suspect a human being would [find]…next to impossible to do," said Jer Thorp, an artist who helped develop a system for arranging the names. In the end, the relationships were entered into a computer and an algorithm was developed to arrange the names appropriately.

Thorp told Spark that he thinks the arrangement makes it a memorial of our time.

"Because our lives are so concerned with social networks, especially in technology, relationships that make up our lives are in the forefront," he said. "And it only makes sense that these things start to be embodied in a memorial."
