One of the motivations i build lanes.pm (a project management tool) was to counter that the only information dense UIs still being around seem to be spreadsheets / table views. Tables have their place but also lots of drawbacks for many workflows. One other great example is ableton live and a few other pro video/ 3d/ music suites. Especially ableton live is as dense as possible while still feeling elegant without tripping over or feeling fiddly.
