This bit of nostalgia really caught our attention. A german hacker or “inventor” as we were called back then, came up with this interesting concept. He would project an image on to the moving blades of an Autogiro, relying on the POV effect to make it appear complete. While this is not the same system of utilizing POV that we currently use, it relies on the same principles. It looks like he’s hanging the projector or “magic lantern” from below the Autogiro, using the length of the rope to hang it as a focusing system. Were this to have actually gone into production, it probably would have really freaked people out. If only he had had access to something along the lines of the ceiling fan POV system.

[update: Why didn’t we look around for this earlier. It was brought up in the comments, there is in fact a POV system for R/C helis. http://www.nightgraphix.de (translated)]
