Helium-cooled superconducting coils, typically made of an alloy of niobium and titanium encased in copper cladding, create magnetic fields ten times stronger than similar-size permanent magnets can muster.
It's encased in aluminum alloy but has a similar metallic look to the Titanium Powerbooks that have proven so popular for Apple Computer (nasdaq: APPL - news - people ) over the last few years.
And yet, the Titanium interior is pretty artful, a sinuous composition in soft-touch materials, alloy-like painted trim, textured fabric, that piano-black plastic assuming your Steinway is made by Mattel and lots of electrons.
