project_Coded Ornament: Contemporary Plasterwork and the use of Digital Technologies_Aperiodic Strapwork
The aim of this element of the project was to develop a series of low relief strapwork designs which did not rely on this traditional ‘periodic’ repeat system. Through the use of a tiling system developed by Roger Penrose in the 1970’s, patterns were created which are ‘aperiodic’ and therefore never repeat. Based on only two units, these types of patterns can have a rotational symmetry, but can also appear random. The two units can also be arranged in an infinite variety of configurations, enabling unique designs to be created from a minimum number of components.
Digital technologies were used to visualise the designs, and to create the tooling from which the physical plasterwork was produced. Two full-scale pattern generating systems where finally produced.
