Bra Cup-Size Choir Interactive
Bra Cup Size Choir
Ok, this was very cool and very simple. The La Senza lingerie company created an interactive application called, "The Bra Cup-Size Choir," that allows you to see women from cup sizes A-G singing in bed. This allows you to generate your own melody or you can try the pre-rendered "deck the halls" song.
