The dangers of boredom

It's been a long Yom Kippur weekend. Even though I have a lot of homework to do, I haven't really done it. Instead I've been doing this:

I'd been meaning to do this for a long time. It took about an hour from setting up the camera to saving the final JPG. Trivia: I'm playing Tredici, and I'm holding the same hand in each picture. Note: I did not actually play a four-player game of cards by myself.

Last night, because I had nothing better to do, I went with my sister and our friends to a practice for the youth group fashion show. It got really boring so we decided to wander around the campus of the school where I had gone for nine years. Surprisingly, several gates that should have been locked were wide open. For the first time since the end of eighth grade, we walked the hallway (not hallways, but hallway) where we spent much of our junior high years. We peered into the four classrooms; all have changed. They seem to have more desks. Other things should have been locked also, most notably the doors into the school office. We went in for a bit and saw their new(?) teachers' lounge, complete with comfortable(-looking) sofas and a nice new TV. Even though many things have changed, it was still nostalgic.

What do you get when you combine a cloudless mosaic of the earth during the day, a similar mosaic of the earth at night, and a composite satellite image highlighting cloud cover over the whole world? You get a portrait of the earth as it really looks right now: World Sunlight Map.
