In 2012 Banham curated and designed "Cluster' an exhibition exploring the thematic 'clusters' of street naming. With this project he proposed that this was in fact one of the first forms of 'urban branding' in that it was aspirational in tone. As part of the 2015 Melbourne Festival he was selected one of the Melbourne Art Trams, on which he featured an assortment of these cluster forms. His interest in this is both typographic (as they are glyph-like forms) as well as cartographic (as they are map-like forms).
