Overlapping 'radial' patterns of black lines rotated a bit differently over a
background plane of 'bozo' or other patterns.  Of course variations were
tried, like bright lines, etc. later on when the subject came up again.
I'd say your technique makes for a more true moire pattern.

I would define it as what the sound might be if you heard one when first
seeing it, but I don't really know the origin.  Ever seen Star Trek (TV) where
they had a display near Spock's control panel which was a couple sets of
radial lines rotated one over the other.  Same thing.  Guess they had that
effect in the '60s too.

Not sure how that would be, yours was quite bold already.
