It's a cool thing to do, but not new. It's usually called stacking and
there are a few program that exist for doing just this, less the photoshop
busy work. Tesla Coils are a great use though.
It was called averaging when I used it.
It reduces random noise (in the background) and in the presence of small
(one pixel rms) random camera motion it can reduce the aliasing between the
detector pixels and the image at the expense of some resolution. Not much
of a problem these days with megapixel detector arrays, deep AtoD
convertors and poor/cheap lenses.
