3D rendering. In the background there are four tanks holding coloured liquid, from left to right yellow, red, green and blue. Glowing liquid from the yellow tank is poured into cube molds, the cast cubes are then put onto a conveyor belt and darken as they cool. The other three tanks are connected together, the pipe coming out of their junction is transparent and visibly contains cyan fluid. That fluid is then sprayed onto the cubes on the transport belt. There are two spray showers, in between the cubes are rotated.
