An interesting gunsight

But probably not terribly practical… looks incredibly fragile and more than a bot wobbly. But it *does* look terribly sci-fi. Now if the little floating glowing dots could be made to hover in space like that but without an actual physical support – as is often shown in “holographic” displays in sci-fi movies – then we’re finally have an explanation as to how Starfleet personel can accurately aim their sight-less phasers: they have holographic sights that are only visible within a restricted field of view.
