Light show

Yesterday morning, as I was getting ready for a zoom meeting from my office, I noticed the color of the trees rippling, so I shot a quick video. Later I realized I didn't know what was going on - and still don't. At the time I thought that the wind was pushing the trees toward me and into shadow, but on closer inspection that's not what was happening. Now I'm guessing that the shadow was coming from something else, perhaps the steam from a chimney (it was quite cold)? A friend I sent it to asked if the trees were blooming and I sent them this. Splendor!
