Three Dollar Quill

I had a kind of rough day today, so so far I've just made a tiny amount of progress on writing up the most straightforward way to have four dimensions; trying to follow what Dewdney called the "principle of similarity" when working on the Planiverse. Even if, as I suspect/worry, a lot of stuff will eventually need to be thrown out, the basic stuff I'm reviewing now should be pretty solid. For now, though, I need to get to bed soon.

Good night.
