裝置藝術
In the 1970s Geiger, an abstract artist, began to include representational elements into her work, and use photographic engraving, photomontage, assemblage, sculpture, and video. In the 1980s she concentrated on painting, and in the early 1990s on cartographic imagery cast in metal, and iron archive box constructions incorporating plaited metals and hot-wax painting (encaustic). Besides painting and engraving, her current work combines Installation art with video. In Rio in 2006, Geiger constructed an installation, "Circe", that included a scale model of Ancient Egyptian ruins and performance video; the installation was recreated in 2009.
