The Poser figure creation and rendering software also had a bunch of unique / idiosyncratic UI elements including the horrendous memory dots concept (mentioned somewhere else here) and camera controls [0] that were unlike any other 3D modelling software. I still remember switching to Daz Studio for figure creation and 'getting it' almost instantly because it used a recognizable UI.
