As one who has worked with lasers for many years, you'd be amazed at what
the general public thinks are lasers - combine a mirror ball and a fog
machine, and people will argue for hours that it is a laser show. Even the
small moving-pattern disco spots that many clubs use are perceived as lasers
by many. Sad how scientifically illiterate the average person is. And,
almost any large laser is water-cooled - they develop a tremendous amount of
heat. We actually had to run hoses from the nearest bathroom into the
planetarium to host an OmniScan (full-dome laser projector) demo a few years
ago.
