Reflexes are reactions onto a certain stimulus. The program was denominated Reflex because it responds to sound waves with motion it has more than twenty different alternatives for visualizing sound. These can be freely composed thus obtaining a much higher number of image variations. There are two groups of surfaces. The first group contains indicators basing on audio physics. In this case it is the sound wave or the spectrum, obtained through FFT transformation, which appear graphically.The second group bears the name Macro, in which an imaginary world seen through a microscope appears. The tiny creatures revive through sound. Their motion and its pattern correlate to the different features of the sound. If there is no sound, life stops if there is sound they start to move about or swim jointly between the frameworks of their virtual territory. The program can be used with live music, through the help of an external microphone enabling a visual background of live performances.

This program is part of an interactive installation. By talking or singing into the microphone letters pop-up from the ground and after a while they fall back. High sounds (for example: whistle sounds) start to float and raise and make the letters leave the screen. In this installation we are using a sound-processing program (PD), wich repeats the parts of the words, arrange them into a composition. Returning sounds creates repeated movements in the group of letters.

Spectrofon is a video work wich I've created using a custom made software. The whole video was recoreded in real time, no post processing. The basis of the program is the splitting of incoming sound into ranges. Fast Fourier Transformation (FFT) is most suitable for this task. After splitting the incoming signal into frequency ranges, the program is able to visualize these graphically. This process can be done in both ways, converting sound to image, and image to sound are both possible. I also used some sound samples wich had been generated from still images. The generated montage is build up from the texture of distorted images and the rythm of the abstract music.

The formation of patterns from different sound waves was analyzed in an experiment. Salt was sprinkled onto the top of a vibrating box, which through sound effects - aligned into different forms. Most interestingly, upon the overtone of Buddhist monks, the sand rearranged into Mandalas the sacred symbol of Buddhism. This was the moment when I started to show interest in the mysterious connection between image and sound.
The computer enables the audio-visual representation of the data set making sound visible. This program is a sound-image synthesizer. It indicates the sum of three sound waves in a periodic scale. This is a very primitive transformation, enabling interferences to be seen on the monitor.

While reading a text one uses his or her finger not to get lost among the lines. A particular relation builds up between the reader and the surface of the printed letters. This program creates an illusion. Under out virtual finger the letters become alive. Our touch leaves marks on the printed-paper.

Whales are orientating according to ultrasonic waves with the principle that the time lag between the emitted sound waves and their reflection is linearly proportional to the object between the emitter and he receptor.
This relationship can also be observed at the echo-effect. The larger the distance between the sound-emitter and the reflecting surface, the more time it takes to for the voice to be heard.
If we put a light source near a camera lens, we can observe a similar phenomenon. Objects closer to us appear lighter, whereas objects further away darken in proportion to the distance. If we reverse this process, we can obtain the surface of a 3D image. This program also applies this principle by using the Night-shoot mode of the camera. The result is a 3-D surface exposed to the original video signal is projection - the picture becomes relatable and observable from different angles.

Zen Balls
This program is an instrument, which simulates bouncing balls: they make a sound while hitting the ground. Balls return to their starting points so they will be moving perpetually without losing energy. The ten balls sound five different tones as they reach the ground. Balls drop from different heights turn to timeless cycles pulsing in time.
