Music and Numbers

I have always been fascinated by math; I even contemplated getting a second certification to teach math.  This website, Music by Numbers, has two pretty cool programs that you can download to your iPhone or PC to use.  The program that can be used on the iPhone scans UPC's and makes a little musical number out of it.  I played around with it and it is fun to use.  I'm just sorry I didn't think of it first!
