Here are links to a few sites which are not (necessarily) dance-related but I though you'd appreciate.
I try to check these occasionally to make sure the links are still good, but I make no guarantees.
Please let me know if you find a "dead" link.

• Zot Hi haArets (This Is the Land) - (1935) The first sound movie produced in Israel (then Palestine, of course).  Produced by Baruch Agadati (choreographer of Hora Agadati).

• Do-Re-Mi - dancing breaks out in the Antwerp (Belgium) train station.  Okay, so it's not quite as spontaneous as it appears - it was run by a local tv station as a promotion to find someone to play Maria in their upcoming production of Sound of Music - put together in only two rehearsals!  But it just feels so good - watch it in the morning to start the day off with a big smile (thanks, Eve!);
• Tractor Square Dancing (really) - there are multiple clips available; I picked a few:
  One of the longer clips;
  This one has more formations than the other, but the video quality isn't good.
  One of the shorter examples, but clear;
  This time the drivers are dressed for Wizard of Oz;
  And another, which tells more about the tractor square dance story.

• "Google Exodus" - a YouTube for Passover;
• 100 Movies, 100 Quotes, 100 Numbers;
• Really, really impressive juggling;
• Breathe In, Breathe Out - this is an ad campaign for Greenpeace - but the photography is kind of cool;
• Granite State of Mind - by a co-worker;
• A new take on Mozart by Grupa MoCarta (and when you enjoy this one, follow the links to some of the other videos by the same group - Jackson, Mambo No. 5, Titanic, Policja . . . ).
