A living 3D museum of an entire city - and its residents - could be created in the UK, after the idea made the shortlist for a prestigious design award.
The 'Arc Project' is one of ten ideas which have made it onto a list of 10 finalists for the 'Playable City' Award.
The £30,000 prize was launched by Watershed in October to "surprise and engage audiences by bringing a sense of wonder into public spaces".
The 10 shortlisted ideas were chosen from a total of 93 entries from 24 countries.
They include the 'Arc Project' idea by Ivana Basic, Kyle Macondald, Gabriella Levine and Jack Kalish of New York City.
The project would see a series of 3D scanners installed in booths around Bristol to create the augmented reality "museum of life".
The project would let visitors be scanned - and "special viewing bubbles will allow anyone to see both themselves and the life size imprints left by those who were there before them".
Other ideas include the Baloonometer, which is what it sounds like - a giant installation made of balloons.
This idea would be to "invite the residents of Bristol to rediscover their spirit of playfulness. By bursting some balloons."
The team behind it say it would be "a colossal crowd-controlled installation using balloons, microphones and fans. The city can collaborate to play: using phones and microphones to move the balloons into a safe house or a container full of spikes."
The full list of 10 ideas can be found below:
"A city-wide conversation taking place through street furniture – bus stops, post boxes, rubbish bins and even lamp posts can talk. Objects are ‘woken’ and chatted to by testing their unique reference and, in the online hub, inhabitants will be able to follow their city’s on-street debates."
"Larger than life building blocks with embedded sensors will come tumbling out of a tip-up truck touring the city. People of all ages and backgrounds can pick up the blocks, move them around, colour them in and shape them to build their own city of dreams."
"A site-specific interactive pavilion and immersive environment, constructed using 3D scans of personal objects provided by the public, representing the different relationships people have with the city ."
"A colossal crowd-controlled installation using balloons, microphones and fans. The city can collaborate to play: using phones and microphones to move the balloons into a safe house or a container full of spikes."
"A series of 3-D scanning booths (reminiscent of twentieth century photo booths) will be positioned throughout the city. Visitors will be able to get their bodies scanned and contribute them to a digital version of the city. Special viewing bubbles will allow anyone to see both themselves and the life size imprints left by those who were there before them."
"Icelandic musician Björk caused a sensation when she released her latest album as an iPad app. UK’s Fred Deakin goes even further, releasing his album as a series of installation experiences in locations around the city, mixing music, light and generative interfaces for a musical experience that is as new as it is immersive."
"Inspired by Ludwig Koch’s classic field recordings of birdsong, a number of digital birds will be installed around the city. Wirelessly connected to the internet, they will emit a range of simple melodies based on tweets and messages sent to them, for example the tweet “#birdsong #castlepark beautiful day” would be interpreted to produce a beautiful melody."
"Cities already host large scale and big impact sporting events, but with Robot Runners comes an opportunity to take part in a massive city-centre spectacle involving up to one hundred robots. Players work together to complete tasks and earn points, controlling the robots via a smartphone app connected to a central server. Each game lasts around 30 minutes, is non-competitive and requires no training."
"The modern city is full of display screens. Most show advertising content, some provide public information such as weather or travel updates. Playscape is a proposal for the first ever infrastructure of public digital displays that provide free public play. Situated around the city and reactive to weather, time and events, Playscape screens will give passers by ideas and rules of simple games they can play there and then on the spot."
"The Jolly Brolly Mystery is a fun way to explore Bristol while solving a murder mystery - even on rainy days. Whenever it rains in the city a new clue will appear at an undisclosed location, which can be picked up by a GPS enabled umbrella. There will be a prize for those who solve the mystery."
The winner will be announced in January, and should be ready by the summer before an international tour.
Clare Reddington, chair of Playable City, said in a statement: "We've had the connected city, the green city and the smart city, but we've yet to embrace the Playable City.
"By launching the Playable City award we wanted to show how cities can be fun and easy to play with in a free and open way. The strength and diversity of the applications we received from artists all around the UK and beyond shows that the Playable City has a bright future and one we are very excited about."
