good wireframe 2

here is a tidy wireframe of the most recent way the tabletop display could work. on first approach, the things floating are the decades themselves, the 100 year timeline. once a decade has been activated, all its equals sink, still visible, but obviously a step away. the active decade then spills its years across the surface of the table. this process repeats once one of those years has been opened: its contents spread across the surface while the previous level sinks. each of the separate experiences from a year can then expand in its own way to the surface, or be active several at a time, for a multi-user experience. people at the table can be looking at different years within a decade, or objects within a year, but at this point, they can't be looking at different decades. the levels get too confusing.
