Here's my thought on the top bar (T.1/G.1) - I think the official header (Ecotone) should be top left, along with subheader (Nature of the Site, Building Community, el futuro) and introductory text. I've included sample text (from the paper-in-progress). The fonts/colors/sizes can definitely change (bring on the comments), but I like how it establishes a clean, professional feel. This leaves G.1, currently Andy's space, open for a nice image/rendering. It should size proportionately with the space taken up by the header/text section, and possibly carry a small caption in the bottom corner (i.e. "native grassland," "kids running in front of car," etc.).
With all of the images coming together for these boards, it's nice to have the title establish the white space. That is to say, we will be able to add much to the board without it feeling "too busy."
Let me know if this works for you guys. If all is well, then I can begin putting together introductory statements for the three boards.
