Christian Blandhoel is a Norwegian visual and audio artist.
He has quite a collection of self-customised guitars which form his "Sonics" series of art works. These aren't guitars for conventional playing. They can have any number of strings, oddly-positioned pickups, springs as bass strings, pickups behind the bridge, etc. Some don't even seem to have a neck as such.
For more of his work please see here and for the guitars specifically here. Much of it is in Norwegian, but I still found plenty to look at and thought it was utterly fascinating.
