The Reuleaux triangle was developed by Franz Reuleaux, a German engineering scientist, who believed in the potential for good design technology to contribute to human emancipation, the dissemination of knowledge, and the common good. The term reuleaux triangle refers to a curve of constant width based on an equilateral triangle and can be seen represented in some of the drawings of Leonardo da Vinci. Desks based on the reuleaux triangle concept have three curved sides and the rolling geometric arcs of this design are viewed as an optimum shape for small group collaborative working, seminar activities and meetings. Reuleaux triangle desks were first introduced at Aberystwyth in 2013 with the aim of enhancing students' experience of small group teaching activities. This design has proved to be especially popular with students and staff.
