In SU(3) color space we are used to thinking about a flow of color.
At the algebra level, the Lorentz group consists of two copies of su(2), so one can ask oneself if there is a similar way of thinking about the spacetime structure of scattering amplitudes.
In this presentation I answer this question with "Yes", and present the "helicity flow method". I further argue that this method opens up for shorter and more intuitive ways of calculating with Feynman diagrams.
