Saaz in farsi has two meanings. It stands for (any) musical instrument, and also stands for the suffix "-maker". It is a result of a research about extending the virtual instrument onto the screen and furthermore into the hands of the performer. At the current state of the work, a gestural input unit is used to steer animated lines in a 2D space. The lines intersect and based on the dimensions and characteristics of each intersection point a sound is made. The result is an audiovisual performance, an improvisation on a set of algorithms where what you see is what you hear.
