Another winner.

I notice a tendency for folks to model both the earth and the terminator
line as vertical.  While it is an accurate representation twice a year
(spring and fall equinox?) I think it might be more interesting to look at
the earth in mid-summer.  Try tipping the earth's main axis by 23 degrees or
so (hope I got that angle right) to illustrate things like why the sun
doesn't set above the arctic circle in the summer.  Just a thought.

Nice movie.
