"Block by block, [patterns] emerge: The way people drift toward the shady side of the street on hot days; [...] the way walking speeds are slower at midday than before or after work; the way people don’t like to maintain the same walking speed as a stranger next to them; [...]."

"A couple of years ago, as a test of the walkability of London, I set out from Trafalgar Square — the official centre of the town — one Sunday morning to see how far I could get without crossing a road or going over the same place twice. It was almost 17 miles before I ended up going round in a circle."

"This is the idea behind [Exhibition Road's] cross-hatching, which suggests diagonal paths across the road. It obviously has a strong subliminal effect, because you really do see people crossing diagonally."

"To try the soundwalk, right click the download link and 'save as'. Sync the downloaded file to you MP3 player of choice, wait until the next time it rains, and take it out with you. Put your headphones on, press 'play'."

"The city is under occupation by intelligent microbes, Martian bodysnatchers, mind control rays - you can't tell the resisters from the wholly invaded. Do not attract attention to yourself. Choose routes where the least number of people will see you. Use alleys and back paths. Walk calmly through crowds. Show no emotions. Ignore commodities. Hide your hunger."

"Rolling at a constant speed, in a straight line, Tweenbots have a destination displayed on a flag, and rely on people they meet to read this flag and to aim them in the right direction to reach their goal."

"The Drift Deck (Analog Edition) is an algorithmic puzzle game used to navigate city streets. A deck of cards is used as instructions that guide you as you drift about the city. Each card contains an object or situation, followed by a simple action."

"Joyce Walks is a psychogeographical tool which generates walking maps based on routes from James Joyce's Ulysses in any city in the world using Google Maps."

"Walk Score calculates the walkability of an address by locating nearby stores, restaurants, schools, parks, etc. Walk Score measures how easy it is to live a car-lite lifestyle - not how pretty the area is for walking." Includes the UK.

Generates walking routes within a few UK cities, optimising for low noise and air pollution.

"There was a street of intact and handsome old industrial buildings, a billboard advertising the new Lexus, and roads and pavements eerily populated only by traffic cones, like a scene from a post-apocalyptic film."

"Funded by Transport for London Walk London has worked with the local authorities to develop an impressive network of quality walking routes."

"The goal of this project is to develop a reusable and behaviorally founded computer model of pedestrian movement and crowd behavior amid dense urban environments, to serve as a test-bed for experimentation."

"[The homebrew DS game] reads the names of the hotspots in your immediate area and turns them into enemies which try to take over your wardive-cristal. Try to fend them off with your touch pen, put your shields up. And don't just stay in one spot."

"The Legible London project proposes to change the existing fragmented approach to walking information into a single reliable, consistent and authoritative system." [...] "Encourage 'mental mapping' by connecting areas, regions and transport systems."

A monochrome map of approximate walking distances between central London Underground stations.

"The first aim of the London Pedestrian Routemap is to encourage walking in London. It does this by providing a simple, memorable picture of key walking routes in the Capital. At present there is no such map."

"[Scientists] set some ants off on a foraging trip along a tunnel, but once they had reached the food their legs were manipulated to either make them longer by adding stilts, or shorter by partially amputating them."

"Of course, it is understood that if the tall man has only got a weak stick or umbrella in his hand [...] he would use his fist to strike his opponent in the face or over the heart in order to disable him."

Random people who've walked every street of their city. "Twenty-nine-year-old Phyllis Pearsall covered London's 23,000 streets on foot in a year in 1935. She walked 3,000 miles, charting her progress while mapping every street."

I wonder when these are going to start becoming live-action zombie-hunter games.

"Wearing high heels, suffering an injury foot and, especially, having a few drinks, are activities likely to set the device off by accident."

Social lurching, and the apotheosis of Internet meet-ups. "Relax all the muscles of your face and de-focus your eyes. Anyone who comes into eye contact with you should see no recognition or expression in your face."

Facetious new tour leaflets at Tate Britain, which looked like they were planted by a stalker - design your own, and get it added to the collection, with a VIP pass thrown in.

"The connection between the body and the world that walking exemplifies has begun to fade as we spend more and more time isolated in technologized cells [...] trapped in a culture that sees unstructured time alone in the world as inherently unproductive."

Hacking the body's vestibular system with two electric-current earpieces, to give video games some genuine centrifugal nausea, rather than the mere illusion of it. Also to make people fall over or walk into traffic.

A nice crow-flies distance-calculator, for walking and bike rides, using the Google Maps API. "Click here if you don't live in Hoboken."

"The octopus used the outer halves of its two back legs in a similar way to tank treads, alternately laying down a sucker edge and rolling it along the ground - making it look like a drifting coconut."

GPS Light Cycles, forcing the other person to crash into your trail or their own. Sounds quite amusingly fractal to play.

Lucid and perilous sleep activities. ''Last week I woke up with the worst taste in my mouth - I had made a sandwich out of beef-bouillon cubes in my sleep."

"One way to grow a Crowd Crystal would be to dissolve non-participant atoms in the crowd with the instruction to stand still when the density of the crowd drops below a certain level."

Interconnecting motor-feedback bright-plastic lumps. "[A] dog can be constructed and then taught to gesture and walk by twisting its body and legs. The dog will then repeat those movements and walk repeatedly."

"Why did the cows amble where they did?" Various factors in the evolution (and thus design) of successful paths. Slopes and sunshine and maintaining walker interest.

Two psychogeographers take turns to follow a succession of random strangers around New York.

"If we ignore aerodynamic effects, we can show mathematically (but won't) that while you'll collect many fewer head drops running rather than walking, you'll get exactly the same number of chest drops, regardless of the speed at which you travel."

Our power-hungry robot overlords need only fit piezo-electric pads into our shoes. Also, brilliantly: using skin-conductivity to transmit electronic business cards through handshakes.

A giant, urban version of the Scotland Yard boardgame, with players running around Toronto's public transport system in coloured T-shirts.

"The city is always one hour wide." - citing Marchetti's Constant; that humans have tended to spend one hour per day travelling, since Neolithic times.

A monkey starts walking on its hind legs, possibly as a result of near-death brain damage. Great photo.

"If the person falls, or limps or shuffles - warning signs of diseases such as osteoarthritis or Parkinson’s - the monitor alerts a computer to send a message to a caregiver." - would also be good for live-action Thief.

Charity text-message Buddha-statue hunt on the streets of London, starting next month. "Discover weird statues, strange inscriptions and abandoned underground stations..."

"A chart showing maximum speeds for some of the more common Hollywood hazards measured against the fastest speeds that an Olympic level human can deliver."

Gallery of maze photos. Oddly interconnected-looking, when shown next to one another.

Looking like a vertically-scrolling video game map. Bench around low lighting column! -50 points!

"They are typically narrow streets without curbs and sidewalks, and vehicles are slowed by placing trees, planters, parking areas, and other obstacles in the street."

Signless, ruleless inner-city traffic control - forcing drivers and pedestrians to interact at around 20mph, the maximum speed at which eye contact still works; our ancestral top-running-speed.

Showing stations within arbitrary walking distance of one another.
