As a part of his graduation project, graphic design student Christopher West is inviting you to pay him for wearing a T-shirt with a message of your choice.

In other words, he will be a walking billboard, promoting your message.

Every week a new blank T-shirt is put on auction on eBay. The highest bidder gets to decide the message and the design. Christopher will print it and wear it for a full week.

The idea behind the project is to investigate the medium of printed T-shirts and apart from the project's performative aspect, Christopher West is also producing a publication.

All the T-shirts will be exhibited at the graduation show at the Rietveld Academy in Amsterdam. You can also see them on eBay, where a new one is added every week.

TRASH: anycoloryoulike is a remarkable art intervention for urban beautification and environmental awareness.

The project is developed by the New York based artist Adrian Kondratowicz who created colorful trash-bags and distributed them to members of his local community.

By using the new bags instead of the traditional ones, the standard piles of trash on the streets were transformed into vivid sculptures of color.

The project has been a massive success and the community around it seems to be growing and spreading to other cities.

And naturally, the bags are 100% biodegradable.

Critical Run is a sweating debating format for criticism.

The concept is developed by artist Thierry Geoffroy and the purpose is to train the awareness muscle by discussing a topic while running. Distances are relatively short and participants are often dressed in normal shoes and clothes.

Topics discussed so far include: "Does art has an impact in political decisions" and "optimism at the age of global war".

Critical Run has taken place in New York, London, Istanbul, Athènes, Paris, Siberia, Copenhagen, Moskow, Napoli and den Haag.

Check the website for upcoming runs.

A subtle intervention by Canadian artist Lauren Marsden in which she knitted covers for street signs on every street which she has lived in Victoria.

The knits were based on the actual size, colors and dimensions of the signs.

In a slightly similar project, Lauren covered a lamp post with images of bark to make it look like a tree.

If you're in Copenhagen before March 15, don't miss the exhibition 'Til Vægs' (To The Wall) at Kunsthal Charlottenborg.

The recently appointed acting Director Maria Gadegaard was asked to take over amid a turbulent time when there was basically no budget as well as an empty calendar and exhibition space to fill out.

Consequently she turned the problem into an opportunity and invited 40 local artists and asked them to paint and draw directly on the walls, thereby avoiding expenses for travel, transportation, insurance, materials etc. Paint was sponsored by Dyrup (a paint manufacturer) thus further reducing costs.

The result is impressive - like walking through an overdimensional visual book with every page offering something new - and the exhibition has received tons of much needed public as well as critical acclaim.

Their work can be found in galleries as well as urban spaces around the world. However, their unique urban tags are never up for long as they are quickly removed - or 'stolen' - by fans.

In 2006 AOL foolishly released a text file on one of its websites containing twenty million search keywords over a 3-month period. Before realizing their mistake, the file had been mirrored and distributed on the internet.

None of the records on the file are directly personally identifiable but each user is identified on the list by a unique number, which enables the compilation of a user's search history (New York Times actually managed to identify some of the users).

Now, the history of one of these anonymous users as been made into an experimental episodic documentary called 'I Love Alaska'. The movie tells the 'true search history' of User #711391 - an obese religious woman from Texas, who is looking for a way to rejuvenate her sex life. She cheats on her husband with a man she met online but regrets her deceit and dreams of a new life in Alaska.

I Love Alaska is made by Lernert Engelberts and Sander Plug for MiniMovies - a platform for documentaries made for the digital age.

The exhibition documents and presents 99 actions - or 'urban interventions' - that instigate positive change in contemporary cities around the world.

Common activities such as walking, playing, recycling, and gardening are pushed beyond their usual definition by international architects, artists, and collectives featured in the exhibition.

Two of my favorite actions included in the exhibition are (P)LOT by Michael Rakowitz and Football Field by Maider López (see images). The exhibition also includes the brilliant Camera Surveillance Players and the excellent PARK(ing) project by Rebar.

If you can't make it to Montreal, you can view the 99 actions on the exhibition website. The site also contains a user-generated section which makes it possible for anyone to submit their own actions. The most popular ones will be featured in the physical exhibition later on.

Moving Forest is a park on wheels. The park is made of trees in shopping carts that allow the public to rearrange their own little park.

The forest is created by Dutch architect firm NL architects in response to the lack of green nature in contemporary urban environments - which in the case of the Netherlands, more or less amounts to whole country.

Moving Forest was recently installed at the Experimenta Design event in Amsterdam.

Causas Externas is a young design collective based in Barcelona who create experimental objects that play with the border between interior and exterior.
