Some people might dismiss the water curtain stop sign as a touristy gimmick for the city of Sydney, Australia, where it was recently installed, but a slew of YouTube videos prove otherwise. Unfortunately for Sydney, truck drivers have a particularly hard time keeping track of signs, finding themselves in disastrous situations that delay traffic and cost the city tons of money. In order to avoid more bridge accidents, the water curtain stop sign was installed as a final message to truck drivers not to pass through.
Envisioned by Australian engineers, the water curtain stop sign is powered by a laser that projects the universal image onto the falling water. What might be a big investment will in the end save Sydney a lot of money. Plus, it wins in the looks department.
