This week's selection of art websites tracks artists who have forgone the mediums of paper and canvas to leave a lasting impression on the walls of the galleries and spaces they draw in.
Morgan O'Hara -
Morgan O'Hara's "seismograph-like drawings" embody movement, dance and human relationships. Her drawings are made in real time whilst watching or taking part in events (such as a live Kung Fu battle, a piano recital, a soccer championship or a slipper maker) and echo patterns in the observed movements.
Sol LeWitt - http://www.massmoca.org/event_details.php?id=27
Conceptual artist Sol LeWitt produced more than 1,200 wall drawings during his prolific and influential career. LeWitt rose to notoriety for his geometric pattern wall drawings - which were often executed by teams of people drawing to his very specific instructions.
David Tremlett - http://laudanum.net/tremlett/
Installation artist David Tremlett revels in creating site specific drawings that gradually disappear over time. Tremlett's wall drawings are inspired by the spatial context he is working in; his works in pastel crayons trace the architecture, proportions or volumes surrounding them.
Dan Perjovschi - http://www.perjovschi.ro/
Somewhere in the midst of drawing, cartoons, graffiti and political satire lies the work of Romanian artist Dan Perjovschi. His wall drawings provide social commentary on recent events and tackle controversial subjects such as abortion and politics.
Justine Ashbee - http://www.justineashbee.com/
With a pen in one hand and inspiration in the other, Justine Ashbee creates spontaneous, amorphous and organic-looking drawings on walls.
