I like, I like, I really like. Love the "scale of the universe"
  videos but this is the first interactive one that lets me
  control it. Everybody needs something that's bigger than

  people its the weather, some people it's the scale and scope of
  the Universe, from the foam to the parts so far away light ain't
  gotten here from it yet. The awe of the scale of the universe is
  what keeps me humble - the "universe is on my fingernail" type
  thing. "
