Intricately detailed Quake III map of the Simpsons' house

I find it hard to believe someone could have such an obsessive love of both The Simpsons and Quake III, that they would feel it necessary to make something like this. I wonder how it plays. How have I not seen this before?

With luck we’ll get to see it in Quake Live.
