Philip K. Dick's Scramble Suit

Introduced early in the second chapter of his 1977 novel, "A Scanner Darkly," as follows:

"Basically, his design consisted of a multifaced quartz lens hooked to a miniaturized computer whose memory banks held up to a million and a half physiognomic fraction-representations of various people: men and women, children, with every variant encoded and then projected outward in all directions equally onto a superthin shroud-like membrane large enough to fit around an average human."

I wonder how it's coming along....
