Two horn speakers are rotating on a high speed, thus creating
the typical Leslie-effect, a special kind of Doppler effect.
The soundfile used for the Leslie is the morse sound of the
Russian satellite Sputnik, which is continously beeping on
different volume levels. In the center of the rotating speakers
is another speaker from which the two letters can be heard,
that frame my publication „Space is a place“:
one by an anonymous comissioner, asking me to produce a public
art piece for outer space and my answer, which is the starting
point for the whole book.
