I always am amazed by how chaotic point-to-point wiring is. Diodes hanging here, a capacitor there, with no real sense of organization. It's such a contrast from the ordered appearance of a PCB.
Yeah, those things were obviously designed to be hand-soldered, no automation possible. I guess this also makes them easy to repair ("easy" as in "not fiddly", obviously you still have to know what you're doing).
