* A video cam that records reality no matter what (an artifact)
* A cam that records the reality in the eye of the recorder (not necisserily(?) an artefact)
* Cams record the rality in the eye of the viewer...
* Cams record the Illusion in the eye of the viewer (the way we are used to)...
and so on and so on....
Specifically, I am using an Illuminati cult in my campaign that record their break-throughs into reality with video-cameras... I'm just looking for an excuse to "non-initiated" viewers too see reality through their surveillance tapes....
