My 5-year-old has set up a selection of large rocks on the railing of my back porch, which my kitchen faces.
In the kitchen, there is a small TV with a red status LED, which due to the window construction reflects twice.
As I naively walked into my kitchen, the only person in my house awake in the early morning, the rocks and lights lined up in an alarming way. I got quite a start.
(I know the picture isn't great quality ... I think the phone camera didn't want to focus on reflections. Also I zoomed in to hide my kitchen clutter.)
edit: Clarifications.
