Systems theory for the algebraic - a calculus of perturbations of systems in feedback flux. CTL has followed the directive inherent in the writings of Maturana et al as to the possible effects of perception as allowed modifications in the internal state, through the direction of enclosing the world/perceiver pair into one unit and investigating the possibilities of intruding upon this directed pair by manipulation of the perception stream. The intrinsic next step is to identify the perceiver and perceived, to accept the feedback loop from perceiver to perceived inherent in the system and to investigate the effects of interfering only in this feedback vector, perturbing it for various effects.
There are many forms of feedback, the prime axes of positive (exitory) and negative (approximating) feedback being but two. Complex systems brought into feedbacking configurations often search out states of static or dynamic balance, the minimal energy configurations of stable orbits, but also fall into so-called chaotic trajectories, skittling across the configuration landscape. A common technique for investigation is to allow the manipulation of various parameters in the system, to investigate the changes in the state and the dynamic behaviour of the state as the parameters are adjusted. For this a detailed knowledge of the system is required, access to some of its primar state variables is needed. We choose to act not upon the body of the system but its vector of feedback; we add a probe that interferes with the loop and look into the effects that can be obtained - often with no explicit knowledge of the structure of the system itself.
This accords strongly with the precepts upon which an investigationof the public individual can proceed; we can only rely upon and areonly really interested in their behaviour, their interactions, their perception and control vectors, their large scale biomechanical activities. This line of research will take us further in our reearches along an axis that we have left relatively untouched to date.

Some projects:
- Mixer only Sound: connecting the output of an audiomixer back to itself should, in the ideal case, lead to a high pitched (too high to hear?) feedback whine determinedby the transients in the various intenal amplifier stages.With some degree of subtlety, manipulating the feedbackparameters allows the localising and tracing of varioussounds intrinsic in the mixer.
- Sound plays VideoLoop: A classic example of complex feedback is the video loop camera-monitor. Passing the feedback trough an audio mixing device allows an audio source to interfere in the loop, adding inflections to the feedback. The generation of orbitting transients and the introduction of signals to maintain unstable systems are two directions of research.
