Check out this huge display on wheels from OMDM that saw action at CHITEC ‘08, dubbed the E-K50 II. This LED display is mobile and would certainly be creepy, assuming Big Brother uses it to make announcements to its citizens in public areas. I think this is one great moving advertising medium, and will definitely find a place in glitzy places such as Vegas instead of relying on those old trucks that carry nothing but a static billboard on them.
