   THE ROLLING GREENS
   Images and black space. No type on the page at all — the logo is artwork
   and there is nothing clickable, so no webfont and no external request.

   Laid out as a wall, not a slideshow: photos sit in rows, side by side,
   edges nearly touching, a couple lapping over each other. The one place
   that keeps real air is the logo at the top.

   Nothing here is a system. Widths, gaps, laps and tilts are knobs.
