<p>In the present paper the mathematical model, introduced by Crutchfield [1], for video feedback performance is outlined. The two dynamical fractals observed in our video feedback experiment have been described. The first one shows the five-fold symmetry. Its spatial form relates well to the one which was simulated numerically by Andersen [2]. The second one consists of black strips with dislocations and rotates with the velocity of 0.2 1/s^-1. The spatial form looks like a modern picture and its spatial time evolution correlates well with Chopin music.</p>
