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.

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.

Oeps Crew are two anonymous girls (supposedly) from Copenhagen who create small graffiti-inspired motifs using plastic beads

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.

Check the Oeps Crew website for documentation as well as gallery updates.

"But what are we going to read?"

During Buy Nothing Day, adverts in a London tube train were replaced with white paper by The Space Hijackers - a group of anarchitects who oppose the way that public space is being eroded and replaced by corporate profit making space.

Greece based designers Kathryn Sanderson and Aristidis Skarpetis are behind the online store ALBINO, which sells a variety of white T-shirts that you can colour-in yourself.

Each shirt comes with 3 color markers of your own choice and you can add additional markers to your order.

Albino is not exactly the first ever to sell colourinable tees online. Even Marks & Spencer have a similar product. However, Albino is solely focused on one kind of product and they've managed to create a unique and personal universe around it.

Currently, Albino tees are printed in more than 70 different styles.

Too bad the tees are for kids only.

A few months before the senseless events on 9/11, the performance-group eteam took part in the LMCC artist in residence program that had studios on the 91st and 92nd floor of the North Tower of the World Trade Center.

On the night of March 29 2001, the eteam created a temporary light-sculpture using illuminated windows in the North Tower to spell their name in capital letters. To create the letters, they needed 279 'dark' and 127 'light' windows on 7 floors (from 89th to 95nd). The event was carried out in collaboration with 12 offices located on the respective floors.

During their stay, the eteam did another site-specific event called Quick Click in which they made photographic portraits of people in the studio from a helicopter hovering outside the building.
