I think those are often the most enjoyable projects, the ones where you start out just literally thinking "hey, is this possible? let's find out!"
Having absolutely no intention of ever writing my own engine, I'm constantly in awe of people who manage it. Also I totally misread the author / project names at first and thought you'd called it Zoidberg, so have to admit to a small amount of disappointment there lol.
Thanks for the share!
