Fig. 3: Programming the platform by introducing different input patterns during execution.

a For every frame in a video, the centre of mass (CoM) of a BZ oscillation was calculated using the blue channel of the frame, and then as these CoMs translated between frames, we plotted their translations using straight lines. Thus, each of the plots in this figure represents how the BZ oscillations moved across the arena. b In these four rows an experiment was performed where the same input pattern was applied to the BZ medium for 30 min. c In the following rows, two different experiments were performed where the pattern inputted to the BZ medium changed dynamically. In the first case, it iterated in a loop where every minute-long iteration inputted each of the four patterns in a sequence where each pattern was inputted for 15 s. d In the second case, each pattern was inputted only once: initially 0 for 10 min, then nothing for 5 min, and then 1, 2 and 3 for 5 min each.
