Iner Souster and the Experimental Instruments He Lives With: This is a fascinating blog showing the creations of this possibly quite eccentric Canadian guy and his even more eccentric instruments! As he says: "This is a collection of instruments that I have been building since the year 2000. Some of them are functional, some just plain suck."
They include a few guitar-like stringed insturments... well, vaguely guitar-like, I suppose. There's a fair few other non-stringed instruments too.
They all look fantastic from an artisitic point of view. How musical or playable they are is another matter that I couldn't possibly comment on!
