25,000: One small click for a scientist, one giant clatter for Open Science.
This is a memorial screencap of the moment 25,000 of us had signed the We the People petition to the White House for public access to publicly funded US research. Download its original size for a copy suitable for printing and framing, A4 or letter size in the US. Scientist and Open Access advocate David Liao, @lookatphysics on Twitter AKA "D. L. from Holmdel, NJ" on the petition, was the 25,000th signatory. The moment was captured, and first documented on Twitter @openscience and on Google+ by the Open Science Federation.
