^ That is incredible.   At first I assumed the Lego neck lent itself mainly to microtones but that thing can do it all.

Uli Roth developed his Sky Guitar that expanded the guitar's higher registers by increasing frets and expanding neck reach, and eventually adding a seventh string: "It takes a little getting used to but it's worth it because you're getting fully analog high notes that don't get on any other guitar" . --Uli Jon Roth

This looks pretty cool as well

The world's largest pipe organ was built between May, 1929, and December, 1932, by the Midmer-Losh Organ Company of Merrick, Long Island, New York. It boasts seven manuals and has 1,439 stop keys, as well as 1,255 speaking stops, 455 ranks, and 33,112 pipes! The organ weighs in at approximately 150 tons. The most impressive stop on the organ would have to be the 16 foot Ophicleide, which is the world's loudest stop. This stop has six times the volume of the loudest train whistle.

^ Very cool . . . and I'm talking about his hair.
