From 2008 onwards, Banham has produced the typographically themed "Oblique" series. "Orbit Oblique" (2008) was a typographic tribute to the animals lost in space research (1949–1990) during the space race. The second "Utopia Oblique" (2009) was based around the utopians who have used language and/or typography to express their ideal notion of society. In 2016 he published "Cashcow Oblique", which centred on a typographic survey of the marks used by real estate developers through the current real-estate boom. It took the form of a poster, folded down to a small book format. 1000 copies were printed and distributed free all across Melbourne.
