1) Colin does not actually fit into the space that we're working in. He's too tall, so it's pretty funny to watch him squash to get around the telescope and onto the laser table. From where he's standing, the roof is about shoulder height on him.
2) I'm smiling because I've just managed to unscrew the thing that was stuck into this spot, and have not yet realized that the new thing I want to screw in there is not going to fit. By 3 mm.
