So, I have thought about the car float over and over and over, almost to the brink of insanity, and it isn't inspiring me at all. I don't know why. And the roundhouse idea didn't do it for me really either. So, I have been doing some more experimenting and have hit upon what I enjoy most, and that is inglenooks. I present the latest idea, a full 5-3-3 inglenook, which have just spent the best part of an hour switching, and good god it was fun! Sorry for all the dithering. I'm sure I will come back to the float one day.
