Here's the full video from the post-flash mob dance launch of Mark Cousins and Tilda Swinton's fantastic 8 1/2 Foundation, which works to bring kids the gift of cinema on their 8 1/2th birthday... There'll be a full explanatory story up on indieWIRE later today, though the video from the Filmhouse in Edinburgh explains it quite clearly as well...
