This 2D simulator draws a side-on cross-section through a glowing crystal cavern: stalactites hang from a rough ceiling while clustered crystal growths rise from the floor, each cluster pulsing with its own emissive colour while water droplets drip steadily from the ceiling into darkness below. Drag the base-glow slider to brighten every crystal's core emission, raise the mist density to fade far clusters behind cave haze, and click any crystal tip to send a bright flash rippling through its facets before it settles back to its ambient pulse.
