this is a bit off topic, but is there a term for the effect you see when you shine a laser on a surface? Kinda looks like thousands of tiny dark particles moving about, I don’t know how to describe it, it’s cool tho.

Interesting tidbit on speckle patterns (interesting if your into firearms accessories), it’s the mechanism used to create the reticle inside an eotech [or any other real] holographic weapons sight.

Just thinking about this topic.

Hank wanted us to be creative…right?

Here is an idea, a light with a wider variety of types(or spectrum) of light, that worked along with improved/aided human vision (like with Gordi Lafarge’s visor in Star Trek Next Gen)., so that humans could see a wider spectrum (or different types) of light. Sort of the way some night vision already works. Much of the technology already exists.
