Watch 123Movies. Heliocentric uses time-lapse photography and astronomical tracking to plot the sun’s trajectory across a series of landscapes. The entire environment feels to pan past the camera whilst the sun stays in the centre of each frame, enabling us to gauge the earth’s rotation and orbit around the sun. As the Suns light becomes disrupted by passing weather conditions and the environment through which we encounter it, it audibly plays them as if it were a stylus.
