Nice concept and a good looking shirt.
I hope you don’t mind some feedback. It doesn’t work as a circuit layout: 1. Acute angles are usually forbidden. I suppose that may change if 3D printing becomes the norm but it is a real no-no when you are etching. 2. Each color is all shorted out in two big nets.
One could argue that art shouldn’t be constrained by such trivialities, but a hazard of my profession is that I can’t look at this image and not see those flaws.
