Could be dangerous adding all that water to the road surface, unless you used something like a water repellant covering.

Saw the idea of projecting on to water years ago and often wondered what real-life applications it could have. So I guess this is it. Any more examples on how this could be used?
So cool, in the UK, you would just need the projector and use the regular rain 😉
