My office in the Grohmann Museum at Milwaukee School of Engineering gets lots of direct and indirect sunlight in the morning.

Today as I was getting ready to leave for my 10:00 class, I noticed that not only had the usual shadows of my coat rack appeared on the wall (“shadows” plural, from sunlight reflecting off multiple windows at various angles) but that there were also a series of whooshing light reflections flashing across it, reflections thrown upward off the windshields of vehicles driving next to my building on the street down below.

So I paused for a moment or two (10 seconds, to be exact) to record some of these moving light reflections on video before heading out the door.

Fun, right? I knew you’d like it!

The audio in this clip is so weird, though. The traffic sounds in the background aren’t in reality anywhere near as loud as they seem in this video. My office is on the second floor of the Grohmann Museum, and while you can always hear traffic noise from below, it usually fades into a background hum that I don’t even notice. But the microphone on my new iPhone is so powerful that not only can you can hear what sounds like wheels clunking over the twin manhole covers below my office at around 1.5 seconds in but you can also even hear me taking a nice, deep breath at around 7 seconds!

So, yep, that’s all I have for today, just a few seconds of reflected sunlight and shadows flashing on my office wall. Oh, except, I told John T. down in Florida that I’d say “hi” in my next blog post.

Hello from Milwaukee, John! 🙂
