Somewhere between data visualization and civic artwork, these info-driven diagrams reveal wealth disparities in the centers of America’s second and third largest cities. Herwig Scherabon‘s project, titled simply Income Inequality, uses a matrix of blocks (minimicking magnetized iron) to highlight rich and poor neighborhoods.

The city grids form a recognizable backdrop for these axonometric representations, allowing viewers to read the baseline built enviroment against the overlaid information. In turn, the millions of stacked pixel blocks end up forming an alternative landscape of skyscraper-like structures in the urban environment.

The net result is a map of the city’s invisible patterns and correlations shaped by power, money and time, revealing inequalities and mechanisms of segregation. Above: Chicago’s infamous low-income South Side (with Lake Michigan for reference). Below: poor areas of Los Angeles located directly next to the downtown core.

The final presentation was mounted on a pair of wooden boards with the city names shown on the cites, exhibited at the Glasgow School of Art graduate show. Captions on the side give more details on the diagrams.

From the artist/designer: “The two large prints (150x75cm) are visualizations of income inequality in Los Angeles and Chicago and are currently shortlisted for the Information is Beautiful Awards. They are printed on matte Somerset Velvet paper and mounted on thick wooden boards. The images are abstract diagrams of these cities that show a high resolution matrix of blocks. The height of these blocks corresponds to the income in the respective output area.”

“It is part of the design idea to inspire the viewer to look for their own neighborhood or other areas that interest them. I want to trigger a train of thought for what the reasons behind inequality might be. I am always fascinated by the patterns and correlations in the urban fabric. The politics behind urban planning tell us a lot about the people who live in these places and the powers who shape them. I think that it is utterly important to try to unveil the inequalities and the segregating mechanism that we got used to live with.”

Save perhaps lawyers, what is more ubiquitous in modern society than advertising? We are used to guerilla advertisements that promote a product or service for profit or subvert the status quo but many organizations, individuals and guerilla artists have begun putting a unique spin on guerilla action by advocating for important local and global issues. Here are just some of the growing number of subversive advertising campaigns that have been to raise global awareness.

This collection of Red Cross guerilla advertisements touches on a great variety of emergency situations, from ones close to home to others around the world. For the most part they emphasize the living conditions of others who are less fortunate, from those who need blood transfusions to others in war-torn and poverty-stricken nations. Such culture jamming strategies can bring an issue into public discourse.

Homelessness is also a contentious issue in the realm of public debate. Some people advocate more programs and assistance while others maintain the homeless should simply find their own way back to their feet. This collection of homeless advocacy advertisements illustrates the growing homeless problem, much like other creative urban artistic interventions question the status quo. Regardless of your position on the issue they certainly provide food for thought.

This collection of ads on humanitarian interests is not for the faint of heart (the most tame are shown above). Some of the advertisements are extremely graphic and provocative. Still, the messages they carry are therefore all the more powerful and they address some issues that are less frequently addressed in current global discourse including child soldiers, domestic violence and animal rights. Projects such as the melting ice cap mug above are a good example of simple and local ways to advocate creatively for environmental good. Other projects are intended to work more as examples that can be replicated on a global scale.
