Fluxface in Space, organized by artists Gary A. Bibb and Cecil Touchon.
The essentials: Create a work of art about space exploration, photograph yourself with it and upload it to the NASA web site (yes, the government web site), and then submit it to the Fluxface in Space project for exhibition. (Image, top: Angela Ferrara's poster for the event/exhibition).
Bibb and Touchon write on the Facebook Group Event Page for the project: "Gary A. Bibb in collaboration with Cecil Touchon have conceived an exciting new exhibition project for the Fluxmuseum. Using the Face In Space Program from NASA - we are organizing a 'Fluxface in Space' exhibition to be launched into orbit on the last two Space Shuttles!
