Silver Bygone? The installation BYGONE? should be a trip to the future, a reminder of the ÒseaÒ past of Prague. How would the Prague panorama look after the return of the sea to its original height? Description: A telescope-like device, similar to those which we can see at important view-points, would be placed at PetÞ’nsk‡ lookout tower. It would look completely the same as a standard telescope, so that a random visitor to the place would look into it, expecting a panorama of Prague spires and roofs. To his/her big surprise, there would be a view of an endless sea surface. It is quite possible, that there would be the tops of the highest spires jutting out of the water. The telescope would be moveable, and in an ideal case, the perception of the sea would be adjustable to the time of the day, or to the weather. At a close look, a barely audible sound of sea surf would be heard. Technical conditions: Telescope (a standard type could be adjusted, or a laminate replica), SGI Impact, or perhaps also the O2, tracker, LCD display, headphone loudspeakers and various complements. Rose There is a three-dimensional object placed at the Internet WWW server, looking like a tropical flower. Its size, shape and color change over the time depending on the number and character of the people looking at it. A businessman from New York causes different changes than a Japanese student, or a German clerk. The flower lives from human interests and reflects their spectrum. Realization: The shape, size and color of the object are defined by a set of equations, into which the information about the guests - computers which enter in contact with the server, are substituted. The depiction is reached by means of the Java applet. The spectator can see at his page a three-dimensional object, which can be turned by the mouse. Placement: The rose is placed in a virtual, physically non-existing space, shared by millions of people from all over the world, who will be able to enter it on the Internet - www.avu.cz/~silver/rose.
