Say you wanted to make a parade float on a used semi trailer chassis. And instead of the traditional built-up prop structures, you used video all over it, a rolling glass box in effect. How would you imagine it? LED panels, rear-projection from the inside center, fake hologram peppers ghost screens? Laser projection? A combination?
The idea is to make one float that could instantly change themes and update the message, and be daylight-readable. It would mix still images with animation.
If doing the peppers ghost thing, it would mix live performers with projections, say, a futuristic couple in space suits on an alien planet, menaced by aliens or robots or some such. But it has to be daylight visible at typical parade float spectator distances.
