The small balls, between 5 and 50 mm, are made of tightly pressed modelling clay. The pellets are thrown forcefully so that they stick to the surface of the wall, in total disregard to museum hanging conventions. Formal interest resides in the “braking” of matter in motion—how its spatial trajectory is stopped when it hits the wall. Each event creates a residual spot and the accumulated events produce a free and informal whole. The projectiles, randomly assembled on the surface, offer a vision of constellated objects moving in space. The pellets’ distinct colours create different spatial layers due to their chromatic radiation.
