At cruise RPM that effect would be completely lost. There's not a
bird or human alive that can discern stroboscopic effects of more
than a couple hundred cycles let alone over a 1000. Most of us can't
even discern 60 cps.

Birds have much better vision than human beings, and I don't believe
anyone has tested their ability to discern stroboscopic effects.

What using your parakeet as a wing man now in combat sim games?

And the front fan on a turbofan is turning at around 40-50 revolutions per
second, not
thousands.

My phonograph turns at either 33-1/3 or 45 RPM, which is just as relevant to
this conversation as your mention of turbofans.

At any given moment there are thousands of aircraft powered by turbofans in
flight.

The Non Sequitur Kid puts in a surprise appearance.

Yet he fails to state that at any given moment there are thousands of
phonographs in use.

Would be quite useful if it really worked. Of course there would still be
strikes with inattentive and near-sighted birds. ;-)

Entertaining thread this turned into. Anyway, here's a nice illusion.

Concentrate on the + in the middle.
An illusory green dot soon appears.
Moments later, pink dots seem to disappear.
