Harp or Guitar?

I've never seen one of these in my life before - a harp guitar. One of the blokes on the UK Landy forums bought one today, and posted a pic, then had to explain to the rest of us rough types what it was! (Which goes to prove not every Landy bloke is a Neanderthal.. :-) ) He also posted this clip, so we could see it in action:



Absolutely amazing. I've always wanted to learn how to play the harp, but this could just be another option. Gotta investigate.
