Ride the Rollercoaster: Come On, It's Friday

Back by popular demand: the real estate rollercoaster video link. It's free, it's safe for work, it's scary.  Ride it.  What is it?  Housing prices over the past century, plotted onto a rollercoaster.  If the line is too long at that link, or the server too slow, try this one at YouTube.  Sixty-six thousand people have taken the ride on YouTube. Comments?  Thoughts?
