"Isometric" refers to the style of the 3D viewpoint. The x and y axis are presented at a 45° angle, and the camera looks 'down' on the surface diagonally. Escher's work is an example of how an isometric perspective can be manipulated to present an impossible object, such as a staircase that appears to go upwards even though the 'top' stair is connected to the 'bottom'.
