Gary Hill’s ” Klein Bottle with Image of Its Own Making (after Robert Morris)” from 2014 is on display in bitforms Gallery’s Summer 2017 group show. The glass structure is a 3-D representation of the Mathematical form introduced by Felix Klein in 1882. Related to Moebius strips, Klein Bottles are a sort of vessel where both interior and exterior are all the same continuous surface. They are only truly possible using four dimensions. A video is projected inside the bottle showing the glass structure being formed. This conceptual aspect of the video connected the sculptural work with it’s production relates to Robert Morris’s “Box with the Sound of Its own Making” (1961).
