Last night for the first time in a very long time I stayed up all night. I had an idea for a new printer head design and once I started the 3D model for it I could not stop. Finally, at 7 am I went to bed. I was up again at 10 am and spent most of the day continuing with the work. I paused only for food and a nap and finally took a break to watch some tennis with Nicolai who is still taking it easy after having his wisdom teeth extracted earlier this week. The photo is of the Sudbury River which I took last night shortly after sunset on my return commute.
