Our common perception of a graffiti artist is a vandalistic rebel who works through a free venue to spread his message. Although there are many incredible artists who sprinkle our streets and alleyways with colorful, astonishing work, they don’t expect much respect from the common passerby for the work they do- until recently. The public environment, as it always has been, is a venue for artists and people to speak out. Recently artists have used graffiti (or the notion of graffiti) to stimulate thoughtful movement through our public space by addressing topics such as climate change, pollution, and consumerism.

The UK’s Paul Curtis, also known as the "Moose," and Brazil’s Alexandre Orion are taking a new approach to graffiti to convey a sense of "clean," and to inspire pedestrians to keep it that way. Their cue comes from the "Wash Me" message commonly wiped away from the back of dirty semi trucks. They call this reverse graffiti, and they create their work by removing soot, sludge, carbon from exhaust, etc., from the wall to reveal a message.

Moose generated a message in a transport tunnel that reads "Go Gently" to remind drivers of the impact their cars have on the planet. "Once you do this, you make people confront whether or not they like people cleaning walls or if they really have a problem with personal expression."

Orion created a work in a Sao Paolo transport tunnel; his is a series of skulls that also depicts the impact drivers’ emissions have on the planet. As a result of this project, the transit authority washed the wall to remove the public expression. In reaction, Orion created the same artwork on the other side of the tunnel. This resulted in the transit authority cleaning the entire tunnel on both sides. They then continued to resist the public work by cleaning every transport tunnel in the city. Not such a bad idea on all accounts.

Another artist, Edina Tokodi, recently created a work of green graffiti in Brooklyn, New York. Edina saw the idea of graffiti as an opportunity to stimulate positive green thoughts and encourage city dwellers to resurface their connection to nature. She decided to maintain the venue while changing the medium. Her work consists of moss installations adhered to the wall where spray paint might commonly be seen. Using this much less harmful medium, she creates images such as prancing animals, and uses existing imagery to create trees and objects found in nature. The beauty of this medium is that it can continue to grow. As moss receives water from the air, condensation, and rain, it continues to grow as the artwork remains fixed to its site.

When we order a new piece of furniture or new piece of technology for our home, it comes delivered in a box large enough for kids to build a fort in (what I did in an old refrigerator box once). There’s so much packaging that you have to call your trash service and request a special “large load” pick-up. I am ashamed to bring home a plastic bag from the grocery store when I forget my cloth, but how ashamed are we when we request this mountain of waste.

Well a recent graduate of Central St Martins’ Masters Industrial Design Program, Tom Ballhatchet, decided to use the guild in a constructive way. Instead of throwing away all this stamped foam packaging from his new flat-screen TV, Tom decided to construct an entertainment stand. It makes us think of the form of these extruded or stamped packaging part, oftentimes they are the same shape and size or have nice crevices that can serve as storage. My only wish in this project is that he found a way to incorporate the gigantic box and plastic wrap.

With this trend of Zero waste design and seeing packaging as superfluous, we are beginning to see even more products out there that use their packaging in the fully constructed form. Lite2Go’s packaging doubles as the actual lampshade leaving very little waste (the label and instructions for assembly). Designed by Knoed (i.e. know no-end), Lite2go is a good example of their mission statement- “taking into consideration the full life cycle of materials going into the products they design”. The packaging/shade is made of recyclable polypropylene plastic; and the electric cord and bulb can be recycled at the appropriate centers.

The interesting thing about this design is that it is just plain practical. One doesn’t have to be an eco-conscious consumer to see this. Why create extra packaging when it is unnecessary? Although the light is marketed as a green product, it could be marketed just as a light with a fun DIY surprise.

With this trend of cutting down on emissions and waste, we need to think beyond recycling. As recycling requires energy to break materials down into a new usable source, reusing materials for a new purpose is much more energy efficient. I challenge you to get creative with your waste and repurpose some of it at least once before you get rid of it.

Designer Scott Amron has created a catalogue of conceptual products designed to persuade people to use less energy, or at least think about how many things are plugged into sockets in their homes. The experiment is called "Die Electric," named after the insulating properties of a dielectric material. A dielectric is a substance that is highly resistant to the flow of an electric current. The experiment is about powering down, and rethinking the function of electrical components for purposes other than jacking up the monthly electric bill.

The first set of experiments transforms messy power cords into functional household items: "Shelf" (image above) and "ToothHold." Depending on where the outlets are in your home (usually at a functional reaching level), you now can use this cord to have reachable necessities throughout the home. Whether you are reaching for a toothbrush or a book, your outlets are put to greater use. Thinking beyond common functionality, maybe you can even use this shelf as a seat…

The second set of experiments are nothing but aesthetic wall dressings. Their titles insinuate the additional meaning: "Grow Plug" and "Single Vase AC." These houseplant retrofits cover up tacky wall outlets while adding an element of fresh-cut or freshly-growing nature to the room.

The third, and my personal favorite, is simply titled "Off." This is a light switch hook designed so that the it only functions as a hanger when switched to the "off" position. The switch is still fully functional, but the added bonus encourages you to think about your actual lighting needs.

Designer and experimenter Scott Amron has performed and exhibited a large portfolio of functionality experiments incorporating basic principles of engineering and physics while challenging their common conceptions. One outstanding project among these is called "Brush and Rinse," which won a Best of Category award in this year’s I.D. Annual Design Review, a highly acclaimed annual design competition. Scott has a B.E. in Electrical Engineering, and is a declared freelance electrical engineer, designer, conceptual artist, inventor, and founding principal of Amron Exptl.

Check it out. His products don’t cost you your shiniest penny, and they will provide your houseguests with a challenging surprise.

More than 70% of outdoor space in the city of San Francisco is dedicated to vehicle parking. That leaves little space for public activity, public play, and public human parking. This very idea sparked an inspiration in a few young men in San Francisco who decided to intervene by paying the meter to create temporary public parks. Rebar group is what they call themselves and the event is called PARK(ing).

The first event took place on November 16, 2005, when these guys and their buddies rolled into town with a truck bed full of sod. They identified a parking spot in a part of downtown San Francisco that was lacking any sort of public outdoor human space, put some quarters in the meter (thus renting the downtown real estate), rolled out their sod, parked a bench, and enjoyed their afternoon in the park (until the 2 hour meter ran out). They invited all passing pedestrians to enjoy a little time in the sun with them, and take a rest. “By our calculations, we provided an additional 24,000 square-foot-minutes of public open space that Wednesday afternoon,” says Rebar member.

The critical issue the members of Rebar intend to approach goes beyond the excessive amount of city surface area dedicated to private vehicles. They desire to display the paucity of public outdoor urban human habitat by way of temporarily renting this private vehicular space.

It is nice to have trees in the city to clean our air and increase our exposure to nature amongst the manmade construct, but oftentimes these small plots of earth are fenced off. Why not include a place to enter and rest your feet right next to these trees?

In its third year, Rebar’s spactacular PARK(ing) event will take place in cities all over the world. Friday Sept. 21st will be a day that no one could miss while tromping around a participating city. The Trust for Public Land is heading up National PARK(ing) day in more than a dozen U.S. cities: NYC, LA, DC, Seattle, Portland, Chicago, St. Paul, Boston, Austin, Salt Lake City, Tampa, and Miami (for more info to get involved or add you city… click). Additionally, a slew of international cities are lined up to participate on this monumental day including: London, Paris, Barcelona, Valencia, Munich, Toronto, Melbourne, and others.

So in response to this information, ReBar, myself, and our community are calling on you — artists, activists, and citizens — to temporarily take over private city parking space and turn them into ephemeral public parks. Get in touch with your local coordinator, invent your perfect mini park, and build it on September 21 along with other enthusiast worldwide…and don’t forget to invite you friends!

Remember the logic word puzzle from middle school: “Which is heavier, a ton of feathers, or a ton of lead?” Some of us answered with the obvious response: they are of the same mass. Others of us got stuck on the materials under reference. For those of you who relate to the latter, I’m here to tell you it’s ok, and there is help.

Many factoids that we hear throughout the day are hard to process and comprehend. These numbers are originally relative to the individual. Yet when multiplied by the masses, they result in dramatically long numbers that are supposed to represent our collective actions on a daily basis. We commonly hear them on the radio, on TV, and in conversation, are we really expected to have the capacity to visualize 6+ digit numbers in our head on the fly?

Photographer Chris Jordan is working hard to help us comprehend these numerical conundrums. “Running the Numbers” is his new photographic series presented to rescue us more visually-oriented folks. These “digitally stitched” images effectively depict these number problems based on our collective consumption. Since our individual experiences are incomparable to these numbers-of-the-masses, it is hard to create a mental picture of massive amounts. For example, 426,000 cell phones are disposed of in the US every day. When the majority of us dispose of one every one to two years, it becomes difficult to understand the collective numerical value. Well, if you agree with me and really love to visually understand what these numbers look like, then Chris has already decided to help you.

In this image are 426,000 cell phones, the number disposed of every year by US residents.

This image is made of 106,000 aluminum cans, the number of cans used in the US every 30 seconds.

This is what 60,000 plastic bags looks like, the number used in the US every 5 seconds.

Now grab this last image, drag it to your desktop 30 times, and open up each one next to another. This is equal to the number of plastic bags we consume in the US every minute! (For you number people, that is 1,800,000.) With this image, it is easier to imagine what this amount looks like taking up space in our designated drop spots (aka landfills), and how they might be affecting our congested ecosystem.

“If we can more deeply feel the meaning behind numbers like these,” says Jordan, “maybe that will enable us to make more conscious choices about the behaviors that lead to them.”
