The wind is in from the Canadian tundra and the air has gotten drier and much colder — almost like winter. And that dreadful Senator Boxer from California has engineered a shortage of pseudoephedrine. Californians! What do they know of sinuses?
I woke up the other morning and decided that the curves I’ve been thinking about are called sinusoidal. That just means they have pockets and peaks. Undular, if you will.
So, I googled, “sinusoidal origami,” and dang! There’s Leong Cheng Chit there, ahead of me. Foiled again! Curses!
