Another website for those who want to crowd-source the funding of their art project:
For instance this project: Museum of Non-Visible Art
“This is a conceptual art project by Praxis, curated by Vallejo Gantner, artistic director of PS122 in Manhattan. Praxis is the collaborative art team of Brainard and Delia Carey, and in this project, James Franco has collaborated with them. Praxis has been in the Whitney Museum Biennial and James Franco has exhibited his art work internationally.
The Non-Visible Museum is an extravaganza of imagination, a museum that reminds us that we live in two worlds: the physical world of sight and the non-visible world of thought. Composed entirely of ideas, the Non-Visible Museum redefines the concept of what is real. Although the artworks themselves are not visible, the descriptions open our eyes to a parallel world built of images and words. This world is not visible, but it is real, perhaps more real, in many ways, than the world of matter, and it is also for sale.”
