Particles drift up from the city horizon. Collect them into charges, emit beams, and attach mirrors & prisms to bend and split the light. Every beam fades in ~14 seconds — keep feeding. The energy reservoir drains constantly; if it empties, the installation scores zero. Trigger the PULSE to showcase: decay freezes for 2s and you are scored on beam length, closed loops, symmetry, color harmony and reservoir left.
