The Cosmic Laser
A show of colors, lights and
"The Cosmic Laser
Concert" is a show/voyage of geometric, multicolored tridimensional
images projected by a laser ray equipment, that is being
exhibited in the Brazilian Planetarium, from Tuesday to
Friday, with sessions at 20 and 21h and on Saturdays and
Sundays at 19:30, 20:30, 21:30 and 22:30h. This is one of
the five laser equipment in the world - and the public has
already seen the show in the main Brazilian cities, with
The atmosphere is
created by the projection, in the dome, of images reproducing
our galaxy. The almost total darkness is broken by the appearance
of the first luminous points projected by the laser, while
you can hear the "Stratosphere" music by Tangerine Dream.
The laser is projected in red, yellow, green and blue. Spherical
forms appear and they spread via sound-waves effect multiplying
in several designs. This synchronization sound/image is
commanded by an operator, a technological artist, who deals
with 58 buttons available in the laser equipment, to synchronize
with the sound track, taped in a quadraphonic equipment
and that ranges from classic music to Pink Floyd.
responsible for the operation of the laser equipment, explains
that all projected images have geometrical lines.
Each show is unique,
and depends on the public's return. The laser has intense
color and a precise focus, recalling the neon lights. The
images multiply and change continuously: geometric forms,
entwined lines, water reflections, hazes, a ballet of colors
and shapes, all parade through the dome of the Planetarium
allowing multiple association by the public.
A krypton laser
is used in the show, the most adequate for entertainment,
due to its capacity to produce 4 colors. An American Company
brought the show to Brazil. Its owner, Willy Feliu, says
that the same show is going on for over 5 years at the London
and Los Angeles Planetariums, and is being exhibited with
success in the main cities all over the world. Prices are:
Cr$1,500 for adults and Cr$1,000 for children and students.
