This project is heading towards its end. There are still four weeks left of the 20 week exhibition period though. I have trampled a path which is now, with all its windings, divisions and loops, about one hundred meters long. I will prolong the path with four new meters until the 5^{th} of November. The mean temperature is going down quite fast now. The line will probably end quite close to the last plane three.

This is a Google maps image with the five plane threes. I added a temperature curve, drawn by hand. Blue is zero degrees Celsius. The orange curve shows, left to right, the mean temperature on a weekly basis, from January through today, the 15th of October. The path is based on this curve. I have hoped for Google to take an image of the path from above, but not yet.
