Brief
Square tiles cast from a platinum-cure silicone loaded with strontium-aluminate glow powder, poured into shallow 3D-printed frame molds so each pour sets as a flat, translucent slab that holds a charge. Once cured, a UV laser diode is mounted in the pen carriage of an AxiDraw plotter in place of a pen - so instead of inking, the machine traces vector paths in light, sweeping the beam across the phosphorescent surface to "draw" with charge. Wherever the beam dwells the powder excites and holds, so the plotted linework - grids, contour fields, warped meshes - blooms back out as a glowing afterimage in orange, teal, and blue once the room goes dark, fading slowly as the charge decays.
