March Daily Challenge - Sound

Day 13 of MissyMoo's March daily challenge - Sound: Sound is a hard one to shoot, can you do it? What's something you heard today?

I did sound as a theme in the challenge almost a year ago on 06/04/2012, on that occasion I chose to do as sound as a bell. This time round I'm doing an update on the Technology that PorridgeWog chose and nearly made the mistake of referring to it as the current technology, but of course downloads and MP3 players/iPods are the current technology.

Pretty patterns from light reflecting off a CD. A special prize goes to anyone who can identify the CD!!!!

I only managed to post yesterdays blip today, so please have a look.
