When I was at Bournemouth University I studied linguistics, language evolution, and artificial intelligence . So fascinating and, in my opinion, language evolution never stops, grammar can be\u00a0broken, new communication means are established, and brevity within a physical context is encouraged.Visual languages, i.e. those that communicate with symbols, colour and the suchlike, seem like the natural progression. The use of mobile devices, the expanding urban landscapes, and the movable population of the world means that we will not need a Tower of Babel, we will need visual systems to help us all communicate and get along. It needs to be democratic and accessible by all.Modern visual language started on the streets. Sure, people go all of the way back to caves, and the Egyptians for hieroglyphics but I am talking about alternatives to modern formal languages. Those systems that are found underground and when they hit mainstream do not sit well with the authorities.In ‘The Hobo Code, Propaganda, and Visual Activism’ I wanted to bring together 3 examples that get people thinking about what has been and what is to come…Hobo CodeIn\u00a0the mid-to-late 1800s times were really tough for some people. Poor men, typically those finding difficulty finding jobs, jumped\u00a0onto trains, riding freight cars, traveling\u00a0around the USA\u00a0looking for work. Over time these people became known as ‘hobos’ (for some unknown reason). These transient workers found a way to help each other out \u2014 a series of glyphs known as the \u201chobo code\u201d that they would leave at, or near, properties that they stayed at. It was a coded support system.An example of Hobo CodeThe following video goes into the Hobo Code in more detail.The code even gave birth to new ways of marking territory.\u00a0\u201cWho is Bozo Texino? chronicles the search for the source of a ubiquitous and mythic rail graffiti\u2014 a simple sketch of a character with an infinity-shaped hat and the scrawled moniker, \u201cBozo Texino\u201d\u2014 a drawing seen on railcars for over 80 years. Fascinating.It was the precursor to graffiti and tagging.Graffiti & TaggingI grew up in England in the 80s. I remember my first trip to London in around 1982 or 1983. My father and I drove up to Hounslow and we took the tube into town. As we rushed by the suburbs of Greater London I started to see tags and colorful graffiti. It blew me away. I had to know more. It drew me into the hip hop culture.It was a marking of territory and a statement of personality.‘INFAMY’ is an intense journey into the dangerous lives and obsessed minds of six of America\u2019s most prolific graffiti artists. Directed by acclaimed filmmaker Doug Pray (\u201cHype!\u201d and \u201cScratch\u201d) who teamed up with writer, publisher, and graffiti guru Roger Gastman, the movie takes you deep into the world of street legends SABER, TOOMER, JASE, CLAW, EARSNOT, and ENEM.Advertising, Propaganda & Street Art ActivismAdam Curtis’ ‘Century of Self’ talks about propaganda and the birth of Public Relations and modern marketing to create the huge retail economies that many nations use as a barometer of fiscal health. Here is episode 2 (go and hunt for the others) that really delves into this.https:\/\/vimeo.com\/75779119Propaganda mechanisms have been hijacked in modern culture with everything from flash mobs to pirate radio to street artists that take beautification of environments and communication of important opinions and messages to the next level. The Artist JR is incredible in his vision and execution.’28 Millimeters, Women Are Heroes’ in Rio de Janeiro in 2008Here he is talking about his Inside Out Project.And, then we have those that won’t ever conform. KIDULT is one such person.Graffiti is not simply an artistic expression, graffiti is a protest, a scream of anger which has always claimed the right to the city through (re)appropriation of the commons and the public spaces, including streets, walls, and vehicles of transportation. Streets are in the hands of all and through graffiti, I aim to claim both the gratuity and access to my\u00a0production. The streets are the main support of my protest and the biggest free art gallery.Evolution and progression does not come from permission in visual language. Keep your eyes open on the streets. You’re likely to learn a lot.***Nikolas Badminton is a world-respected futurist speaker that researches, speaks, and writes about the future of work, how technology is affecting the workplace, how workers are adapting, the sharing economy, and how the world is evolving.
