Happy 400th!!

In honor of the fact that today's Abstract Thursday Challenge is the 400th, the optional theme is "Celebratory".  I collect music boxes( the ones with mechanical movements are preferred),  The one I chose to use today is the only hybrid I have.  The display is powered by electricity, but the musical movement that plays "Love Story" is mechanical.  It was given to me by a dear friend after his wife died because he heard that I collect music boxes and he wanted me to have something to remind me of her.  The display changes color constantly when it is plugged in and it has always made me think of fireworks, so I think that it fits the theme for today's challenge. Thanks to Ingeborg for hosting.......
