Joaquin Rodrigo, the blind composer who wrote the very popular Concierto de Aranjuez, once said the ideal Spanish guitar for composers would be a "strange, fantastic, multiform instrument with the wings of a harp, the tail of a piano, and the soul of a guitar."

I think I found one. It's actually weirder than what Rodrigo imagined, but then he didn't have YouTube. Jeff Esworthy put me onto this, and it's creeping me out....
