Lens less Pin Hole NBTV camera?

There is a big following for taking photographs with pin hole cameras, (without any lens)...some even have multiple pin holes! .........

Some of the photos obtained are amazing although exposure times are long. The pin hole cameras are even made out of paint tins
A one gallon camera
I wonder if anyone has ever heard of a NBTV camera using a pin hole lens?
Probably the light obtained would be insufficient for any kind of photosensor behind the Nipkow.
It needs a very, very, very slow rotating Nipkow to get a long time exposure, record it, and then play it back at normal 12.5 revs per sec speed....
Just a thought.
