I have a few long gaps in my resume. I spent a lot of that time traveling the world. This isn't just one gap -- there's two or three gaps over the past decade and a half.

I also worked on my own personal software projects during these times, but nothing ever came of them. I don't even have the source anymore. Would it be ethical to put this on my resume under 'Myself company' or something like that? If not, what's a better way to manage this?
