Untitled (IUPUI Letters) consists of a group of five letters spelling out IUPUI, the acronym for Indiana University-Purdue University Indianapolis. The five sculpture pieces have been installed at an angle from one another with several feet between each letter. The sculpture can be viewed as individual letters of the alphabet or together as one large group. The letter enclosures sit perpendicular to the full cabinets, giving each letter a multidimensional appearance.
