I worked with an artist a few years ago, who, in a series of performance events with her artist friends, placed a large blank canvas and paints and brushes in the event space on which attendees or audience members were free to paint what they wished. The canvas was then exhibited at the next performance and exhibition. This may have been idea circulating with young artists for some time, and which has now found its way into museum venues.  The New Museum in New York , which considers its spaces a leading destination for new ideas and new art, currently has the exhibition Paweł Althamer: The Neighbors,  which includes a whole gallery where anyone can draw or paint on the walls and the floors, and whatever you make becomes part of the exhibition: http://bit.ly/1gbRftO

The New Museum also has an online only exhibition series titled First Look: New Art Online,  a monthly series of innovative online projects and new commissions by the New Museum.

The New Museum wishes to become a hub of innovative artistic practice. The New Museum has also conceived the first museum-led incubator program called NEW INC. The NEW INC program, which will launch in the summer of 2014, will be a collaborative creative space with a lab-like environment for the development of new ideas and practices for creatives exploring cross-disciplinary  and technology based projects. The New Museum feels that because such creative individuals and artist groups are exploring work in still undefined cultural areas, that few resources and support systems exist for them, and so the NEW INC program offers a twelve-month residency to provide the needed space and resources.
