@SV: well, this next one should be right up your alley then - but you'll have to stay really focused not to miss all the important bits.
This is cheating! The vid contains so much information (the vid, descriptions, temperature, atmo composition........) that you need to watch is several times, making the real length an hour long!
EDIT: Very interesting. Watching the levels of oxygen for instance makes me aware of how (relatively speaking, naturally) quickly the atmo composition that we take for granted can change. Or the colour of the oceans! The iron and sulfur levels make the colour from green, purple, red... Especially after free oxygen was released. Fire was not even possible until "recently", because the oxygen levels weren't high enough. Totally logical, I just never thought about it. Worth the watch.
