A Swiss Army Knife of a Table

D*Haus’ D*Table is a functional 3D puzzle inspired by the Haberdashers Formula! Discovered by English mathematician Dudeney in 1903, it turns a perfect square into an equilateral triangle by dissecting the square into four distinct shapes. Dudeney’s achievement lay dormant in mathematical textbooks for over 100 years, but when applied to modern design, the possibilities are endless! Functionally flexible, this coffee table adapts to any space while encouraging play and user interaction.
