yesterday I was tweaking my xplanet setup (I use it to update my wallpaper every 10 minutes) and I finally took the time to setup a bump-map (terrain elevation), a spec-map (ocean/land sunlight reflection) and a cloud-map (updated every three hours or so)
when I was done with the new wallpaper settings, I decided to put the new setup to some more use and make a video of yesterday's sun trip around earth (yes, it's not the earth moving, can't you see?!?)
so I created a dedicated config file, switched cloud-map off (it would have been static, I don't keep track of past cloud-maps) and started rendering the earth every 5 minutes
next step was making a video out of it and imagemagick (convert to jpeg), ffmpeg (mjpeg input video codec) and a bit of bash glue (naming jpegs sequentially) did the trick
here it is!
