I 'd like to mention here that I detest that non-canonical spaghetti wiring. Usually when I make a small to medium boards I spend a bit (a lot) of time in a grid paper to route the wiring. Then I implement that design with one-strand wire, stripped for less diameter and flexibility, only in right angles. It's risky but more pretty, clean and I like it. When bridges are needed. I create a square overhang, like a positive pulse. It's very rigid, it doesn't cave in.

I have done larger boards than the one shown, but don't have a picture at hand.
