I did something similar twice. Once when I was younger where I traveled and lived in China and only did a little English teaching. And again 5 years ago, I took math classes in a new city where I moved to for my wife's job until her position was more certain and then I got regular employment.

I've changed jobs and interviewed some afterwards: some employers make a big deal (negative) about these gaps. While others seem mildly impressed that I did something somewhat different. They tend to pay less attention now that a few years have passed. I think it is also because such gaps are more common these days and because losing employees to other companies is probably bigger problem than sabbaticals.
