::LIKE CHINESE WATER TORTURE, ONLY GERMAN. AND ORGASMIC. ::
The exact opposite of Pipedream
is a curtain of controlled drips which form an image as they fall.
From the Babel Fish
"The construction fastened to the cover of the area consists of 128 nozzles, which discharge individual water drops by means of single solenoid valves. A computer program synchronizes the single solenoid valves in such a way that the water drops in their whole, falling to soil, result in a freely definable bit-map sample. A catchment basin collects the water structures disintegrating. By way of a pump the water is continual supplied to the valve construction, so that a closed cycle results."
"Catchment basin." I like that.
