Nice. I did something very similar in vvvv once: https://www.seltzdesign.com/blog/key-visual-jan-henrik-hansen-with-...

I assume that it would work very differently in Grasshopper. In vvvv you can turn the renderer to not clear after each frame and can easily do this sort of drawing with animated lines, but in GH I wouldnt know how to start. Care to give us a hint?
