'PALM' is an acronym of Pathway Language of Mapping, which is inspired by the movement of the northern lights (aurora borealis). The display dynamic patterns of brilliant lights that appear as curtains, rays, spiral, or dynamic flickers covering the entire sky. These moving visual images are resembled in the terms of sound spectra, which allow actualizing a temporal sonic world in panoramic sound landscape is heard as moving texture and timbre in twenty one groups under ten large shifts. To succeed in an approach of the listening perception, the groups of movements by frequency modulations in interlacing texture are shaped selectively through the observation of the 24-hour cycle live cam of the northern lights.
