Austrian–Slovenian border crossing, competition 1990, realization 1991
"The speed of the sinusoidal wave motion depends on the traffic density and the speed of the passing cars. At least one vehicle crossing the Austrian border mark is required to activate the water fountains. The moving WATER ZONE lies across the border, crossing it."
