"Vectorial Elevation" is an interactive art project originally designed to celebrate the arrival of the year 2000 in Mexico City's Zócalo Square. The website www.alzado.net enabled any Internet user to design light sculptures over the city's historic centre, with eighteen searchlights positioned around the square. These searchlights, whose powerful beams could be seen within a 15 kilometers radius, were controlled by an online 3D simulation program and visualised by digital cameras. A personalised webpage was produced for every participant with images of their design and information such as their name, dedication, place of access and comments. View Details.
