The object and video-performance in front of you resemble that of a ladder. Although the sound "ladder" has no real relationship with the image of a ladder when re-created as such, one can't think of anything else but a ladder. The sign's transformation depends on the relationship between the object existing in space and the language used to describe it over such time. It remains coherent enough, though, given that our current communication system restricts our forms from becoming too abstract.
