Aurora Lake

Northern lights over a mirror-still mountain lake

Curtains of green and violet light roll over a ring of dark peaks and pour into the lake below. The sky follows your clock, from a pink dawn to deep night, when the aurora comes out. Drag the mouse across the water to send ripples through the reflection. With music on, the aurora swells with the bass and flares on the beat.
