\noindent This artwork is based on Particle Swarm Optimization (PSO) algorithm. PSO is an evolutionary computation technique developed in 1995 by Kennedy and Eberhart, and it's inspired by social behavior of bird flocking or fish schooling.\\

\noindent Particles in PSO are made to follow a hypothetical point (focal point, $f_p$) moving horizontally (i.e. scanning each row with a constrained random vertical offset); once $f_p$  reaches the end of a line, it goes to the next row; this process is repeated until the entire input image (the Q of the Quarterly) is scanned. As particles trace the $f_p$ , the average colour of the pixel, where each particle is 'flying over', is taken and the colour is reflected on the output image (the current cover of the Q). In other words, the colour of each pixel of the input image changes the corresponding part of the output image to the swarm's average colour as they flock around $f_p$. The swarm's flocking behaviour over the image creates the resultant cover for this issue of the Quarterly.\\

\noindent The technique will be presented in detail at the A-EYE Art Exhibition symposium at AISB50, 1st April--4th April. See website for more information:\\
