Sydneysiders have the opportunity to control the movements of a giant interactive robot from an Intel-powered tablet at this year's Vivid festival.

The Vivid festival – which kicked off on Friday – paints Sydney landmarks in dazzling light displays over its 18-day run. Many of the lightshows will showcase the potential of new Intel technologies as the chipmaker returns as an event partner for the fourth consecutive year.

Festival attendees will be able to control the lighting on Sydney's harbour bridge, or the movements of a "giant interactive robot" from an Acer tablet powered by an Intel processor. Other lighting displays include a digital forest, its centrepiece a 120 LED 3D tubes, and LED-studded boats floating throughout different parts of the harbour.
