I'd discuss the way the flashdark works, but my team of patent attorneys has advised me that a public discussion of its workings could void my flashdark's patent defense.
It's OK, I've been keeping everyone in the dark with it for years now anyway.
As my team of patent attorneys all wear white coats, won't let me out of my padded office laboratory, and try to get me to take myriad medicines, screw them.
Here's the basic concept:
Darkness is simply the absence of light (photons), so you cannot project darkness per se...as that would be projecting the absence of something, which is not typically feasible.
However, as photons are their own antiparticle, when you collide a photon and an antiphoton together, you get an electron-positron pair, which you cannot see by.
Link to experimental proof of concept:

So, using an antiphoton emitter arrangement, we simply destroy all of the photons with antiphotons, resulting in a beam of electron-positron particles instead of light....or, in lay terms, a beam of darkness.
:naughty:
As soon as I work out the niggling details, such as the type of finish, for the copper and Ti versions, and how to keep the beam from destroying everything its aimed at, such as what happened when experimenting with it on the earth's second moon (sorry), etc, it should be ready for production.
Another detail is that the beam would not allow testing of flashlights using ordinary photons...as they too would be annihilated.
I have a second plan to allow that though I can go into if anyone is interested.
