Description: Matsys was hired as a computational geometry consultant by SUM Arch on this residential project to help create tools to design a stair railing. Using a series of user-generated guidelines, the script builds a irregular cellular pattern of apertures on the railing. Based on a field of attractors, the apertures rotate in the plane of the railing causing the entire railing to open towards certain views as a person walks up or down the stair. Dozens of script iterations were explored before the final design was achieved.
