World's Smallest Guitar- 'Nanocaster?'

I guess this has been around awhile, but it's news to me.

The guitar pictured here is SOOOO SMALL...

How small is it? Well, here's an excerpt from a Cornell University Science News article:

"...The world's smallest guitar -- carved out of crystalline silicon and no larger than a single cell -- has been made at Cornell University to demonstrate a new technology that could have a variety of uses in fiber optics, displays, sensors and electronics.

The "nanoguitar" -- made for fun to illustrate the technology -- is just one of several structures that Cornell researchers believe are the world's smallest silicon mechanical devices. Researchers made these devices at the Cornell Nanofabrication Facility, bringing microelectromechanical devices, or MEMS, to a new, even smaller scale -- the nano-sized world.

"We have a new technology for building the smallest mechanical devices," said Harold G. Craighead, Cornell professor of applied and engineering physics who has the directed the work performed by his doctoral student, Dustin W. Carr...

...The guitar has six strings, each string about 50 nanometers wide, the width of about 100 atoms. If plucked -- by an atomic force microscope, for example -- the strings would resonate, but at inaudible frequencies. The entire structure is about 10 micrometers long, about the size of a single cell..."

Maybe, sperm could play this guitar. How does "In vitro guitar lessons" sound? It's good to start playing early in life.
