Sandpainting is the art of pouring coloured sands, and powdered pigments from minerals or crystals, or pigments from other natural or synthetic sources onto a surface to make a fixed or unfixed sand painting. Unfixed sand paintings have a long established cultural history in numerous social groupings around the globe, and are often temporary, ritual paintings prepared for religious or healing ceremonies. This form of art is also referred to as drypainting.

Alum Bay is a bay near the westernmost point of the Isle of Wight, England, within close sight of the Needles rock formation. Of geological interest and a tourist attraction, the bay is noted for its multi-coloured sand cliffs. The waters and adjoining seabed form part of the Needles Marine Conservation Zone and the shore and heath above are part of the Headon Warren and West High Down Site of Special Scientific Interest.
