Shankara Circle is a free, family-friendly interactive art toy. It renders a calming generative boids flocking simulation: a flock of birds drifts and swirls in a natural murmuration under a sky whose colours track the real time of day in Los Angeles, from dawn and midday through sunset and a starlit night. Move the cursor and the flock scatters; an occasional hawk sweeps across the sky. It is an ambient creative-coding visualization and screensaver suitable for all audiences, with no advertising and no objectionable content.
