The HTG byt giving shape is a different breed altogether. I am personally not into very futuristic and innovative concepts, but I must say this guitar caught my eye. The whole fretboard is a touch screen and it is customizable in many different ways, from the fretboard to the picking area.

I am definitely looking forward to try one of these!
