Outside the Lines is a show about how colours inspire and affect our everyday lives. Scientists have found that the world around us is not as random as we might think. Plenty of the changes and fluctuations in our world appear to share a property called the pink noise, and this in turn is a fractal - patterns which appear to govern many of the natural systems in our world. We find out about the wonders of the mysterious fractals with Jonathan Wolfe, founder of the Fractal Foundation. Then we speak with Esa Räsänen, Professor of Physics at the Tampere University of Technology, about how these patterns happen to be an x-factor in making music sound good.
