Designed by mathematician Tullio Regge in 1967, 'Detecma', an acronym for Design, Technique and Mathematics, was the first decor item to be designed using an electronic calculator. The unique shape stems from a parametric "open source" mathematical formula taken from the Dupin cyclide. The result is an organic and ergonomic shape that breaks free from the models of the category. Available in Red, Orange, Yellow, Green, Blue and Grey. Please specify color choice when ordering.
