The annual meeting of the American Association for the Advancement of Science, the AAAS, in San Francisco back in February, included a standard feature of pretty much any science conference — the poster session. Typically, it's a room full of display panels, with researchers having perhaps three square meters to present the words and pictures that will capture the attention of passersby and succinctly explain their work.
