The link below references Yamamura/Lowther as the possible
project originator.

Project cost in time and materials is likely significant.

A project a couple years ago in Speakerbuilder featured a
product called Kerfkore which had kerfs precut into the
the sheeting for bending purposes. Timberflex(tm) is also referenced
as a source of forming bends.
