Eskil created a multiplayer game called Love as well as his own tools. The source of those tools is available and currently being documented.

One thing to note... Eskil is slightly dyslexic which makes spelling difficult for him.

Lexdysic?
Yeah, I know about that.
That is why I love spelling checkers (which still sometimes fail me).
