Relax and play with swirling, flowing colors in an interactive demonstration of fluid dynamics.

Tap to add more color (double tap for even more color), and drag to swirl them around, like mixing paint or inks, or tendrils of smoke in the air. Beautifully smooth animation, and mesmerizing color effects will entrance you!

Shake for options - change the colors used, and the speed of the simulation (or clear/randomize to start over).
