I started experimenting with the arc network diagram technique and found I really like shapes/relationships that arcs make on a linear axis. This is an early version of Composition B^b, and I like this version as it has a bit of a retro-physics-textbook feel to it. I will develop it further into a completed piece, as this was a save from when B^b was a work in progress. The primary colours at first didn't appeal to me - muted, with the black background made to feel slightly more 'blackboard-ish', I think made the wide array of colours less overwhelming and grating to the eye.
