vtxterrelagune, A spiral galaxy sweeps diagonally across a deep petrol-teal and ink field, with an ivory center and restrained ochre and red-clay arms. Two small distant planetary discs balance the spiral at opposite corners, and sparse pale stars punctuate the quiet space between them. The entire image, including the galaxy, planets, stars and cosmic background, is composed exclusively of fine colored sand grains. Dense tiny irregular grain mixtures create the luminous-looking center and softly dispersed arms while retaining a dry matte mineral surface. Use only the Terre et lagune palette. Gentle lateral illumination reveals real grain contacts across the nearly planar artwork; a few shallow accumulations at short spiral-arm intersections make the cosmic structure subtly tactile.
