These floating globes called "Bubble Bobbles" have an embedded tri-color LED that changes its color based on the tilt of the globe. Meant to be placed in a lake or a pool, every passing gust of wind or disturbance in the water causing a resulting color change.

It might be cool place magnets in them, in some configuration, to orient them to each other. Then you could have a group of them all together, in the same orientation, so they change color in the same way. This might result then in a ripple of color as a wave passes through, rather than random colors because each sphere is oriented a different way.
I wonder too if a magnet at the bottom would align to the earth's magnetic field, so even those spheres not close to each other would be all oriented the same way.

I hope that Makers would have the good sense to keep these out of sight of any navigable waterways. Red and green lights are used to mark a clear channel.
What's the likelihood that this could steer a boat astray? Not much. But heaven help you if a Coast Guard vessel sees you doing it -- they work for DHS now.
