Tom released Satellite Eyes the day before yesterday. It's a lovely little thing that automatically puts a satellite picture of wherever you are on your mac desktop. And it's free. You should have a play.
And, as soon as you can, you should try it out on a train. It's magic to watch it update as it sniffs out new locations along the journey. It really feels like you're looking down on yourself as you travel, like you have a superpower, like you're looking through a machine. It's well nuessfetic.
