is a collective, dynamical installation that allows small groups of participants to interact with virtual objects, and with each other, in real time. People are represented by the results of their activities. Optical sensors monitor the movement of the participants' hands. Users weave trajectories by grouping elements and moving attractors sets. The objects compete each with other, each reacting with the other, or provoke the other's verbal or symbolic interchanges. “The objects are not entirely frozen in advance, but it is possible to change their tissues, sources and sequences. What arises is a dynamic system of variable’s quantities and awareness.” (Lisek 2002).
The essential point of stack(meta)Weaver is feed-back. The signs by which its source code is composed get accessible to users’ manipulation and join the others alphabets on the program desktop. Next, their movement causes changes in the source code and so on…
The signals are picked up by the system of sensors. After the digitalization they are sent to the programs that operate the installation. This is the program created by Robert Lisek and Sz.Kuzniarz. Its practical value will only be determined through extensive experimentation. It would become truly overpowering if the system became to rewrite its own source code and transformed itself into something entirely different than it once was.
