on eco-graffiti ii

I have already written here about eco-graffiti but so many interesting things have been found since then it merits a second post. It seems that etching into plants is not the only avenue open to those who wish to indulge in some public displays of artfection. I have found images in moss, printed into snow and, perhaps most cunningly, selective cleaning. It really is amazing what you can find when you know that there is something to look for.
The artist Hanksy's technique of printing into snow is innovative ( and can be found here: http://hanksy.co.uk/page4.html ) but is surely not practical in the UK. Maybe it is intended to signify fleeting moments of art but i personally feel that crude puns are not the best example of art. Edina Tokadi, on the other hand, offers a more sustainable and lasting image in Williamsburg, Brooklyn with images of animals presented in moss. Although it relies on good behaviour from the locals i feel the moss adds a tactile element to the art which, combined with the playful animal shapes, will surely appeal to children and adults alike. Graffiti, for me, is about reclaiming land, transgressing notions of property and ultimately creating more liveable areas for everybody and if you look here i think you will agree Tokadi achieves this: http://tinyurl.com/3cq5psm . On the same webpage the artist herself is quoted as saying that she likes to let her plants "live by themselves" stating that, "from the moment I put them on the street they start to have their own life". Roland Barthes would love this because as soon as the artist is finished with their work it becomes a part of society and open to what other people will do with it; i feel art that is interactive and collaborative is the finest type and sincerely hope the people of Williamsburg have not only maintained the pieces but changed and enhanced their beauty and identity.
Another interesting find on the inhabitat website was this article on reverse graffiti: http://tinyurl.com/29lwg6d . The movement seems to have been started by "Moose" and Alexandre Orion and they selectively clean dirty walls in public leaving an image. The interest from brands such as Smirnoff suggests that this is a phenomena that may continue into the future (after all the worst that could happen is that walls were properly cleaned afterwards as was the case in the Sao Paulo tunnels) and although technically it is illegal advertising when done for branding it is surely a fantastic eco-solution for artists who live in unclean cities. 
If you have seen any interesting eco-graffiti i would love to see it and if you have been inspired to create your own masterpieces i have found a recipe for the moss mixture here: http://tinyurl.com/3q2q6tt . I am so glad that, as Kate Muir put it, the days of "preserving sharks in formaldehyde is over [and] the days of preserving sharks in the ocean are here."
