The You That Is In It was an installation comprising works on paper and an audio walking tour that was on exhibit at the Irish Museum of Modern Art from June 2008 until March 2009. Commissioned by IMMA and the curator Ian Russell, who was working on behalf of the World Archaeological Congress to curate a contemporary visual arts programme entitled Abhar agus Meon. The text of the walk explored notions of artistic process through the medium of a directed walk leading participants out of the gallery space into the surrounds of the gallery. Hallinan commissioned sound artist and musician Caoimhin O'Raghallaigh to score the audio walk.
Each participant was given a work on paper bearing illustrations created by the artist during the process of designing the tour. They were instructed to fold this into a pyramid shape and hold it throughout the walk, as a talisman for their journey.
