@aphyrÉcole des Bro-Arts The DIN, the German institute for standardization, once had an exhibition about what it does and its history. One of the exhibits was a pair of staircases: one DIN-standardized, the other not. The latter was just slightly off, but enough to warrant a warning sign that it would be surprisingly weird (and potentially dangerous) to navigate.
This staircase you're showing, I don't think it's DIN-standardized ;)
