  I'm wondering if this may have something to do
with Nintendo's big E3
 display back on 05'   They had these huge towering columns running with
 little "paks" of RGB leds on them and where creating realtime full
 motion animation on them throughout the E3 show, where it would show
 much of the gameplay and such of their Nintendo DS handhelds, there were
 also some full sized "screens" using the LED's and acting as Television
 sets in effect, the images were only viewable quality from 50 or so feet
 away, but very cool nonetheless, so I'm wondering if perhaps someone
 OEM'd them to Nintendo or other companies and perhaps that is where
 these questions are stemming from? 
You can buy huge truck-mounted mobile LED full-colour displays.  There
was one on eBay a few months back for about ?140,000 B.I.N. which even
included the 60kVA genny.
