Well Duh! :-)
Assuming 4.6 billion years, then if you had 1 sec for every million years the while thing would take 4600 seconds = more than 76 minutes ... and having just 1 sec for the last million years wouldn't be much use...
Not quite the same thing, but I always thought about doing something to Billy Joel's "We didn't start the fire" - you have a ready made subject list - but inevitably someone has already:
Not quite how I would have done it but there are others as well and I haven't watched many yet. Just put "We didn't start the fire" into You Tube and there are tons of them.
if you single step thru it, there are quite a few "iconic" photographs - Time / Newsweek cover type stuff - Kent state, the girl in the road in Vietnam, etc. If everyone included everything they wanted, it would run a lot more than 2 minutes! I'd guess they made it so annoyingly fast to make you go back later and look at it again in more detail.
It's amazing what they managed to squeeze in -- if you added something from one religion you'd get folks saying "but what about..."
The best thing about this is that it makes you think what YOU would include / exclude if you were doing your own version...
