What's the origin of the name? 'Lunatic' is an antiquated and ableist term for the mentally ill, so probably not the best name for your product/company.
I was originally working on a programming language that compiled to Lua, so I named it Lunatic. Later I decided to write a runtime for the language and called it Lunatic VM. We ended up with an actor-based language-agnostic runtime, but the original name was kept though it does not have any connections to Lua anymore.
