A dog-leg is a configuration of stairs between two floors of a building, often a domestic building, in which a flight of stairs ascends to a quarter-landing before turning at a right angle and continuing upwards.

Isometric graph paper can be placed under a normal piece of drawing paper to help achieve the effect without calculation. In a similar way, an isometric view can be obtained in a 3D scene. Starting with the camera aligned parallel to the floor and aligned to the coordinate axes, it is first rotated horizontally (around the vertical axis) by ± ...
Schroeder stairs can be perceived in two ways, depending on whether the viewer considers A or B to be the closer wall. Schroeder stairs (Schröder's stairs) is an optical illusion which is a two-dimensional drawing which may be perceived either as a drawing of a staircase leading from left to right downwards or the same staircase only turned upside down, a classical example of perspective ...

IDEO Labs' interns created a musical staircase during summer of 2011. Each tread played a different sound when stepped on. [8] Johns Hopkins University students turned a Hackerman Hall staircase into a piano, with a new note per step. The Hopkins Robotics Club modified the staircase so the treads played the C scale. [9]
Stair nosing, especially in commercial and industrial settings, are typically fitted with a non-slip surface to increase traction and prevent injury or even death from slips, trips, and falls. The National Safety Council reports that there are over one million stair-related accidents every year. [ 2 ]
working on the design of a new picture, which featured a flight of stairs which only ever ascended or descended, depending on how you saw it. [The stairs] form a closed, circular construction, rather like a snake biting its own tail. And yet they can be drawn in correct perspective: each step higher (or lower) than the previous one.
