Get a hang!

I was only recently introduced to this instrument when a street artist was playing it in Venice. The 'hang' or 'spacedrum' was developed in as recently as 2000 in Switzerland. Can you tell that it is partially influenced by the 'ghatam', among other idiophones? I was transfixed by the sound when I first heard it, mostly because I couldn't figure out how it plays. You'd think someone is playing a string instrument!
