A friend in Australia used the phrase "nuts-and-bolting" to describe what I'm doing now, and I love it: . There are a surprising number of nuts and bolts in the real world, and I've been using wrenches a lot. In fact, a wrench slipped in my hand and I hit myself in the face the other day, and it made a perfectly semi-circular cut on my cheek bone.
Compared to the software world I've been immersed in for 20 years, this is quite a different world. If you have some bolts that are 3 inches long but you need 3-1/2", you actually have to drive to the hardware store and buy some.
I think what I miss most is multiple Undo, though!
