Michal Sedl‡k The object FLOATING WOMAN represents another Prague island in the river Vltava. It should be placed close to the Troja bridge, which is, in fact, a potential auditorium for this object. A recumbent woman, made of stone covered by a plant (probably a moss) is flowing against the stream, while her hand with nails made of stone monoliths, create her natural protection. The site is convenient for the placement of the sculpture, as the river is rather shallow there (fishermen can wade in the middle of it); however the Vltava is quite wild there. Another object called SPIRAL ISLAND is also considered for the Vltava river in the Troja locality, but it should be placed a bit further up the stream, between the racing channel and the Troja bridge. It is a kind of hollow mountain - an island spitting wooden balls, falling down the hill in spiral lines. The project is driven by an undershot water wheel hidden inside the hill, which transfers the power into the ÒArchimedesÕ ScrewÒ, which transports the balls in corridors to the top. It is a constant process driven by natural power.
