Watching the Earth Move.

One of the lesser problems I have at this time of year is that the low sun at lunchtime shines through my office window and onto the computer screen. It means I have to close each of the two curtains in sequence, and I so dislike shutting out the sunlight.

Today, however, after I’d booted up, I watched the screen for a while as the brightness passed across it. It happens just about fast enough to pick up the movement visually, and as more and more of the desktop became visible, it struck me that I was effectively watching the earth rotate. That was neat.
