This work is based on an extension of the classical Voronoi partition algorithm. There is a set of nodes moving through the canvas, with colors assigned to them. Each pixel in the image computes its own color, as a weighted average of the n-closest nodes. Collectors are co-creators in this work. They can choose palette, the range of nodes considered for the color mix, and noise modifiers. They can also create nodes (up to 12) and set their position, velocity, and color, either freely or snapping them to a grid. This opens an unlimited space of possibilities for static or dynamic compositions.
