Basically, you put in your address, and it spits out how long
   the day is (today for me it's 13 hours and 42 minutes line) and
   has lines showing what direction the sun will be rising from,
   and what direction the sun will be setting from. Perfect!

   This is very cool. I've looked for something like this for a
   long time. I always thought it was silly to try to use old
   fashioned coordinates when I live in a HOUSE with an address and
   there's plenty of geo-addressing already done.
