> In one of the photos it looks like on the other party's side there is a projector near the ceiling in the back but then in subsequent photos that projector's light is gone and there's a different, stronger light that seems much closer to their camera/screen. Is this correct? In those cases those are just normal overhead lights, nothing from a projector. The camera is actually in the screen! > Also, have you considered/tried using an actual LCD screen? At our company we're currently dabbling with digital signage devices (for entirely different purposes) and the big ones are quite impressive. Yeah we definitely want to move to panel displays when it becomes more feasible to do so. We haven't yet made a prototype with an LCD screen but I look forward to the day when we can, because projectors are a lot fussier to deal with.
