Peter Worthington has had an amazing life. And his obituary, which he wrote himself, certainly has an arresting opening line.
This is an animation showing all the commercial flights taking place on earth over a 24-hour period.
It's 72 seconds long (quite boring) but if you grab the tab and move it you can see how the concentration of flights changes with the movement of the sun across the earth's surface.
Geeky, I know, but fun.
