The Memotech MTX Series
Multi-Effect Video Wall - Examples
The Memotech Video Wall was very successful and was
installed in many high profile venues, including the
Hammersmith Palais in 1987, with an upgrade in 1990. At that time, this was
the biggest club Video Wall in the UK, consisting of 2, 5x5 matrix displays. You can read about it in
Issue 52 of Lighting and Sound International in the
There is a small "Memotech History of Multimedia"
presentation by Geoff Boyd, available
on his web pages
Geoff's presentation shows the
Video Wall at the Natural History Museum
Memotech technology, at least when it was installed.
(See Slide 7). The photo in the
presentation is of Nick Moore's "Kaleidosphere
The slide does not make clear that much
of the effect was achieved by the
clever use of
mirrors which gave the impression that the Video Wall
was much larger than it actually was, the active
video wall area was "only" a 4x5 matrix of displays.
If you look
closely at the photos below, (courtesy of the Natural
History Museum), you can see that much of the "video wall"
effect is achieved using mirrors. A close up of this
effect can be seen in
this photograph on Flickr, taken by Alan Wilkinson,
courtesy of Alan, you can find a copy of the picture
here. Alan also kindly put me in touch with the
original system installer (Brian Pipe).
Nick Moore and his company,
Brilliant Adventures, have specialised in optical
illusions using mirrors since 1985. In 1991, Moore
designed and installed the "Kaleidosphere"
at the Natural History Museum, the Kaleidosphere also
featured on the BBC's Tomorrow's World
programme the same year. You can view a clip of the
YouTube. However, I believe that the "Kaleidosphere"
was only the optical elements, i.e., the mirrors used in
this impressive display.

information on this display, I was pointed in

"In 1990 Neal
Potter was asked to head up the design team for
Ecology Gallery at the Natural History
Museum. The gallery was opened by HRH The
Princess of Wales in 1991 and set the standard
for the upgrading of the Natural History Museum
during the 1990's."
There, the Video wall display is referred to
as the "Quadrascope at the centre of the
gallery. It tells the story of the Earth's water

The Video wall
hardware was actually installed by Video Power
Multimedia Ltd. then run by Brian Pipe, although
the company has since been dissolved, the
display is still going strong, though I doubt
that it still uses Memotech hardware. Brian has
confirmed that the Video wall hardware was
sourced directly from Memotech and used an MTX
series computer, he also recalls some of the
detail of the system configuration :
"It was a 4 x 5 configuration using Barco
SCM3240 32" diagonal CRT videowall display 4:3
aspect ratio monitors within the bell mouthed
mirrored tunnel that we called a kaleidosphere
The 16:15 was adjusted out to 1:1 by a series of
light boxes around the outside of the monitors."
[Specs for the Barco SCM3240: 15.7kHz (H),
50-60Hz (V) scan rates, 600 pixel horizontal

Photo Centre of Oman
1992 edition of Light and Sound International
reported that "Memotech Computers recently
supplied a 12x8 System 2000 Video Wall to Photo
Centre of Oman. . . . The system comprises 96
Barco SCM2840 MK2 monitors combined with
Memotech Video Wall electronics."
The location appears to be below the Clock
Ruwi, the commercial centre of
Muscat, the image on the right shows how the
clock tower looked in 2009, with a mural having
replaced the Video Wall.
|The Hammersmith Palais
July 1987 edition of Light and Sound International
had a feature on the refurbishment of the
Hammersmith Palais which included a brief
mention of the installation of two 5 x 5 Cameron
(Memotech) Video Walls.
1990 edition of Light and Sound International
had an article which described the lighting
upgrades to the Palais done in 1990 when the two
smaller Video Walls were combined into a single
10 x 5 Wall - then the largest club Video Wall
in the UK.
Tecterran have an
on their website which describes
Bit Bopper, a "Digital
Interactive Multimedia Entertainment System"
that used Acorn RISC processors to generate
audio synchronised computer graphics. The
article describes Bit Bopper
being used at the 1990 Disco Mix Championships
held at the Hammersmith Palais to drive a "huge
50 screen video wall" - almost certainly the
Memotech Video Wall.
