Desktop PC running Windows 7 or XP (64 or 32 bit) at 3+ GHz with at least 512 MB RAM
and a PCI Express slot. The computer must have at least one 6-pin Firewire
IEEE 1394 port. Note that most machines no longer ship with a Firewire port so
you either have to check that it has one or find a plug-in card. If you find a plug-in
card then make sure that the computer has an appropriate slot available and that the slot
is at least one space away from the graphics card so that you don't block the fan.
Both the ATI and nVidia chipsets are supported.
Modern video cards tend to have digital DVI outputs but DVI
cables will only go a few feet. Fortunately, DVI connectors nearly
always have an analog side channel which can be run up to 20 feet without
problems. Much further than that, and you may need to consider going
to a high end component solution such as the
If the output from the computer is DVI you need a DVI to
DSUB adaptor. The cable shown to the left is DSUB and the adaptor
shown is DVI to DSUB.
Projector of sufficient brightness for room.
Projectors come in two broad technologies: LCD and DLP. LCD
projectors will always work with any of our effects, however only some DLP projectors
will work and must be tested in advance.
A brightness of 1500 lumens is typical in a dark room. Brightness
varies with the ambient light in the room, but the only way to tell for
sure if a projector is bright enough for the room is to test it.
Projectorcentral.com is a good place to comparison shop for
projectors although you should ignore the MSRP and price compare at other sites.
Our work should be displayed in a room with low light which does
not vary -- this requirement is extremely important. There should be little or no sunlight, and
no strobes or bright lights near the projection surface. The
brightness of the projector will affect how much light can be tolerated, the
more ambient light there is, the brighter the projector needed to
overpower it. Light levels for the projection should be similar to those
acceptable for projecting a movie with the same projector. If you would be comfortable
watching a presentation or movie on the projector, the lighting is adequate.
In a darkened room, 1500 lumens is typically sufficient. However,
the only way to tell for sure if a projector will be bright enough for a
given room is to try it out. If lighting conditions change while the
system is installed, the system may need to be re-calibrated.
Note, people often worry that the requirement for low light
implies that visitors won't be able to see their way; remember, however,
that the projector itself is a very bright source of light, so when the
projector is on, the room will be well lit.
The projector should be hard-mounted in a place where it will not move nor
be subject to vibrations. Projectors that are mounted high (typical
of shadow configurations) should be mounted upside down. The easiest
way to do this is to buy a model-specific mount. Alternatively, you can cut a mounting
board for the projector which can be done
by the following method: Find screws which fit into the projector screw
holes; place these screws into the projector and mark their heads with a
pencil; press a piece of plywood which has been cut to approximate size of
projector onto these screws leaving marks; drill out those marks and affix
the board to the projector with the screws; affix the board to the ceiling
or high shelf using appropriate fasteners such as sturdy zip-ties, rope,
or metal brackets. Be sure that the projector will not move after it
A Firewire Camera will be supplied with the software. The camera has a standard 1/4" threaded mount
on the bottom and back plate.
Note that if the camera is powered by the 6 pin firewire cable there
is no need for a power connection near the camera. If you use a 4-pin firewire then you need power near the camera.
A camera mount is not provided because such mounts
tend to be specific to the installation. In general, it is best if
the mount has a ball-socket head to give flexibility to aiming the camera.
The mount shown on the left is least desirable because it has only a pivot
head not a ball head like the other two.
6-pin Firewire cabling to run
from the camera to the computer. Runs over 16 feet must use amplified cables
such as these from pccables.com.
For very long runs, you may need to use a fiber-optic repeater such as this one from Unibrain.
Note that laptops do not have 6-pin firewire connections but rather typically 4-pin.
This will work but with the addition of an external power supply for the camera.
Power supply cables for projector and camera,power extension cords if needed.

USB Key (provided).
Our software requires a hardware USB key to
copy protect it. This is provided with the software and connects to
any USB port on the computer
For effects that have sound, speakers should be
provided and pointed near where the participants will stand.
Infrared light fixtures.
For installations that use infrared light, we suggest using theatrical
lighting canisters. We recommend Optima Lighting Par-38
Use 100W incandescent flood lights. These lights put out lots of infrared and visible light.
Because the bulbs put out BOTH visible and infrared light, filters are used to block the
visible light and let the infrared pass. Use Lee High Temperature Filters
HT 026 (bright red) and HT 172 (lagoon blue) along with a diffuser Lee 216.
Camera filter (provided).
A camera filter with the same Lee filters will be provided that will go over the camera lens.
