There are many musical instruments, but until now, you could not master them while working at your office desk! Dan Wieden from Wieden + Kennedy design team has created the Musical Ruler.
Playing the Musical Ruler doesn’t involve heavy breathing, coordination or timing of any kind. You don't even have to stand up! This ruler is one that will impress others and maybe bring your office together in an impromptu, team building sing-along, and is a tool that you can also use to underline your ever growing to-do list.
The Musical ruler is a plastic ruler with printed finger markings and note positions. Sliding the ruler up towards the edge of the desk alters the note, enabling you to play anything from Abba to ZZ top.
