mirrorscope
(gcide) | Projector \Pro*ject"or\, n. [Cf. F. projeteur.]
1. One who projects a scheme or design; hence, one who forms
fanciful or chimerical schemes. --L'Estrange.
[1913 Webster]
2. an optical instrument which projects an image from a
transparency or an opaque image onto a projection screen
or other surface, using an intense light and one or more
lenses to focus the image. The term projector by itself is
usually used for projection of transparent images by
passing the light beam through the image; a projector
which projects an image of an opaque object is now
ususally referred to as an overhead projector. In
projection of this latter form the projection is
accomplished by means of a combination of lenses with a
prism and a mirror or reflector. Specific instruments have
been called by different names, such as balopticon,
radiopticon, radiopticon, mirrorscope, etc.
[Webster 1913 Suppl. +PJC]
Slide projector a projector for displaying images from
individual transparencies (slides), each mounted in a
separate frame suited to the mechanics of the projector.
movie projector a projector which displays a series of
images from a roll of transparent film in rapid sucession,
thus giving the impression of showing a scene with motion
as it originally was recorded.
overhead projector see projector[2], above. -->
[PJC]Mirrorscope \Mir"ror*scope\, n. [Mirror + -scope.]

smoke and mirrors
(foldoc) | smoke and mirrors
Marketing deceptions. The term is mainstream in this general
sense. Among hackers it's strongly associated with bogus
demos and crocked benchmarks (see also MIPS,
machoflops). "They claim their new box cranks 50 MIPS for
under $5000, but didn't specify the instruction mix - sounds
like smoke and mirrors to me." The phrase has been said to
derive from carnie slang for magic acts and "freak show"
displays that depend on "trompe l"oeil' effects, but also
calls to mind the fierce Aztec god Tezcatlipoca (lit. "Smoking
Mirror") for whom the hearts of huge numbers of human
sacrificial victims were regularly cut out. Upon hearing
about a rigged demo or yet another round of fantasy-based
marketing promises, hackers often feel analogously
disheartened.

Breslin c.1975, has been said to derive from carnie slang for magic acts
