  We discuss a new technology that promises large inexpensive mirrors. We argue
that it should be possible to tilt a rotating viscous liquid by perhaps as much
as a few tens of degrees. The tilted liquid parabolic surface is used as the
support for a thin reflecting metallic film. We demonstrate two critical steps:
that a viscous liquid mirror can be tilted and that an optical quality metallic
film can be deposited on a liquid. The advent of astronomically useful tilted
floating mirror telescopes is contingent on the development of high-viscosity
high-reflectivity liquids. It is a good omen that we already have identified
two classes of such liquids; however there remain technical challenges to
overcome before such liquids can be used in viable telescopes.
