The "Spectre" part of my name has nothing to do with Mass Effect, curiously. I devised it more than 10 years ago. In Russian, the word meaning "spectrum" is homophonic to "Spectre", so I came up with it because I thought of myself of a colorful and diverse personality. But I liked the "spirit" connotations, so in English, it became Spectre rather than Spectrum.
As to "Loony"... when I was registering at a blog site, "Spectre" was already taken, so I added "Loony" to it - as in Harry Potter's Luna "Loony" Lovegood. I can act strange at times and draw non-obvious connections, so this also worked well for me.
