Sir, I hold you responsible for my lack of sleep last night! The Lego knitting machine was fascinating enough, but then I saw the perpetual motion machines and one thing led to another. Now I have to work on 3 hrs sleep. Drat and egads!!!

the hypnotic music helps with the "mesmerizing"
I tend to be easily entertained anyway, but that is amazing!!
