A few weeks ago I spent several hours in the Arboretum well after midnight, exploring and enjoying the night air. It was windy, causing the trees to sway erratically; when I looked straight up the clear sky and shifting foliage looked was moving like a the sea. I took the wind audio one of my videos of this and messed with it till it sounded like waves crashing, and added in a nighttime songbird I’ve been hearing.
