Marcus,

Sounds like a similiar system to 3DTV CORPORATION'S. The effect is not
similiar to
Pulfich. It's real 3D! 3DTV's system is less than $150. They are at
WWW:HTTP://WWW.STEREOSPACE.COM if your interested. Oh, and they do have a
system for PAL.

 This sounds like the 3D TV that Sanyo has developed. I did hear a rumour
that
 they were going market a set top box so that any TV could be used. I sent an
 email to Sanyo about it and recieved a reply stating that it as a Japanese
 only product (NTSC) and would need redeveloping for the UK (PAL format), at
the
 moment they had no plans to do so :(
 
 >From what I've read the effect is almost an electronic form of the pulfrich
 effect., taking a single serial sequence of moving images and "slowing down"
the
 view to one eye so that each eye sees the same scene with relative moving
 objects shifted slightly giving a stereo view that is seen view the shutter
 glasses. The Pulfich effect is very good under the right circumstances and
with
 the electronic black box controling the delay instead of the medium density
 filter (in pulfich glasses) it should be better since the box can adjust its
 self based on speed of movement etc.. 
 
 $200 seems very cheap as the cost of Sanyo's TV system was quoted as more
like
 $2000 (us dollars), although at that price you are getting the TV as well..
 
 (Patrick is in New York.. so if any of y'all across the pond can get one you

 can use it on NTSC.. shame I cant on PAL..:(:(:(:(
