Although these archives have held a strong attraction for those interested in the paranormal, more significantly they have had a very powerful effect in stimulating artistic and cultural expressions. T.G.’s photographs have captured the imagination of many curators. His photos have appeared in art exhibits throughout Canada, from the Dunlop Art Gallery in Regina, Saskatchewan, to the Prefix Institute of Contemporary Art in Toronto, Ontario. Internationally his photos were included in the exhibit "Spiritus" at Magasin3 Stockholm Konsthall in Sweden in 2003. In 2005 they appeared in the exhibition “The Perfect Medium: Photography and the Occult,” held at the Maison européenne de la photographie in Paris and the Metropolitan Museum of Art in New York. Later that year they were featured in the Symposium “Dark Rooms: Photography and Invisibility,” hosted by Princeton University. T.G.’s photographs and the Hamilton family’s archives are a major component of the work of Belfast artist Susan MacWilliam to appear in the 2009 Venice Biennale. They are also featured in the book: "Susan MacWilliam: Remote Viewing" (2009).
