When I was a lad, wirewrap was the thing. You can prototype quickly, and make changes easily too.

(It seems like it's still a thing in fact http://www.nutsvolts.com/magazine/article/wire_wrap_is_alive...)

For those interested in working with wire wrap: ebay/aliexpress/whatnot all sell old-new-stock wire wrap wire and the manual wrapping tools. Wire wrap works perfectly on standard headers, but the extra-long headers you sometimes see on arduino shields and such give you a couple more connections per pin: 5 vs 3 if I recall correctly.

It's a really nice way to work, you solder your components onto one of those pcbs with a lot of holes, solder the pins next to em, and from that point on you can wire, unwire, and rewire to your hearts content. Its great to easily be able to undo a connection when you make a mistake.

I would love to try this at some point: http://cpuville.com/Projects/Z80-wire-wrap/Z80-wire-wrap-hom...

Learned this technique in uni ca. 2004 and still use it for hobby stuff. It's nice to have a more stable, noncommittal method!
