Tony Robbin has had over 25 solo exhibitions of his painting and sculpture since his debut at the Whitney Museum of American Art in 1974, and been included in over 100 group exhibitions in 12 countries. Robbin holds the patent for the application of Quasicrystal geometry to architecture, and has implemented this geometry for a large-scale architectural sculpture at the Danish Technical University in Lyngby, Denmark, as well as one for the city of Jacksonville, Florida.Tony Robbin's latest book is Shadows of Reality, published by Yale University Press (YUP), which argues that four-dimensional projective geometry is the mathematical system best suited to describe reality. He is also the author of the book Engineering a New Architecture, YUP in 1996, and also the book Fourfield: Computers, Art & the Fourth Dimension, published in 1992 by Bulfinch Press/ Little, Brown & Company. He has written 26 papers and articles, mostly for peer review publications, and lectured to professional organizations and university departments of art, physics, mathematics, computer science, architecture, and engineering in the United States, in Europe and Japan, including engineering society meetings in Atlanta, Copenhagen, Guilford, and Budapest. He has written a memoir, published by Kindle, called Mood Swing, a Painter's life.Tony Robbin is a pioneer in the computer visualization of four-dimensional geometry. Since 1981, his realtime rotation programs of four-dimensional figures have been useful for obtaining an intuitive feel for four-dimensional and quasicrystal space.Tony Robbin has an extensive website: tonyrobbin.net
