The NYTimes has a slideshow of Hiroshi Sugimoto's Mathematical Forms series - portraits of stereometric models. (More fascinating mathematical visualizations at Banchoff and Cervone's Surfaces Beyond the Third Dimension web site - though these 4D CG visuals are nowhere near as stately).

More on Sugimoto: his other works include long-exposure photographs of wax models, seascapes, and (my favorite) empty movie theaters and drive-ins. Eyestorm has a good interview with him, as well as a book of Sugimoto's 'Theater' series for sale (which, if you're lucky, you can get for $1,250+ on ebay). Here are notes from the page:

This book is the first-ever collection of Hiroshi Sugimoto's 'Theater' photographs. To create each image, Sugimoto would take a long-exposure photograph of a cinema screen for the entire duration of a movie, resulting in a blank white screen. 'Different movies give different brightnesses,' he said. 'If it's an optimistic story, I usually end up with a bright screen; if it's a sad story, it's a dark screen. Occult movie? Very dark.' The project was partly the result of wanting to make a simple form visible: 'The simplest forms have authority, like a blank white light. And how do you photograph that? You need a framework to make it visible. But this is not simply white light; it is the result of too much information.'
