Invisible building

Today I went into Osaka to meet a friend. I arrived a little early at the meeting place, and popped outside to see if it was raining. When I left the house it was sunny, but on the train I had noticed some very dark clouds moving in, and I wondered if it was going to rain.

It was not raining, but it had been. The road was wet. I gazed at the gloomy sky, or what I could see of it between the buildings.



Something really, really odd caught my eye, and I looked harder. Was I hallucinating? What I could see did not make sense. The sky had windows painted on it!

When my brain had finally figured out what was going on and I wasn't feeling quite so bewildered, I pulled out my camera and took a couple of pictures. The first one is above. For the second picture I used the zoom.



I have cropped and enlarged the second picture. If you look closely you can see the faint outline of the building. With my eyes I couldn't.



When my friend arrived I dragged her outside to see the amazing invisible building, but the sky had already changed colour. She could see what I was talking about, but the outline of the building was visible. I had been there at exactly the right moment, WITH MY CAMERA.

How often does THAT happen?
