Kopfschlag

Kopfschlag is a collective and anonymous internet-based project created by an anonymous team. The online visitors are part of it by drawing, writing, erasing and sharing their artworks on Kopfschlag's virtual wall, which can be defined as something between an etch a sketch and the exquisite corpse.
