FAT were responsible for the design of the RIBA's exhibition on the architecture of the Yemen in 1998. The central feature of the design was a black rubber clad box which contained thousands of back-lit transparencies of Yemeni houses within its dark interior. The placement of the images and their multiple reflections recalled the vertiginous quality of the architecture of the Yemen. The shiny surface of the rubber also revealed Arabic words and phrases in matt black vinyl on its surface. As well as the box, a number of other elements places around the gallery displayed further images and information.
