Creating Auto-randomized Signs/Neon/Such! (getting random) (Patreon)

So- I've touched on a few of these techniques in the past, but this goes more in depth, and a few techniques are significantly more straightforward (and *powerful*!?) My previous method is frankly a tad embarrassing in retrospect (as will be all future previous methods!)
Below's the cheat-sheet for how to set up a "randomized selection from a grid of something". In the Math nodes (currently set to "snap"), you just type in "1/X" (where "X" is however many rows/columns you have on that axis), and it results in the decimal you need- it makes a lot more sense in the video.
Some may be wondering why I used 1D white noise instead of the 4D (which includes an additional "W" slider)- and it's just because as far as I know 1D is pretty darn lightweight computationally, and 4D is many times heavier while giving the same result.
Also- I just put it together as a quick-n-dirty demonstration, but if anyone wants the storefront from the ending of the video to use in anything, here's the blend file! It's got the scrolling sign and a couple other randomizing things in there.
