@David Since you asked _"How would you like it if..." I wouldn't take it personally, It wouldn't bother me. Would that have been the case 20, or even 5 years ago, probably not. I started writing a longer answer onion skinned with multiple layers of patronizing CoC style and realized I was writing pretty much how to search more effectively with google and thought F-it breached the CoC and posted just the link.
(*comment not answer above) In hindsight ironically I didn't quote the relevant search phrase. Perhaps showing the search term that I used to find duplicate link I posted eg think of anagrams of dimension... a floor plan blue print would have been better.. (but that lead to result above) .. Will go for option 3 don't comment at all in future.

I'm wondering how I can animate making one ray at a time visible.

@JDługosz You might want to try the animation nodes addon for that sort of thing
I'm looking at the material in a redit post. How do I change the scale of the whole thing? That is, the way it look from some distance away is how I want it to look close up.
@gandalf3 Thanks, I'll look for that.
@JDługosz You could put another mapping node after the texture coordinate node, then tweak the scale there.
Though I typically like to use a mixRGB node instead of a mapping node, with the mix mode set to multiply and the other color input fed by a combine XYZ node. It's a little semantically wonky, but it gives you sockets for controlling scale with other nodes if you want.
Multiply for scale, add for translation
Woops; Blender just crashed. First time for me!
uh oh
@gandalf3 That's a bit advanced for me to follow. I'm just starting this.

Don't worry about it then, a mapping node is just fine
@JDługosz Perhaps this is relevant? blender.stackexchange.com/q/14413/599
@gandalf3 I had just saved. But, I would have expected Autosave to be automatic, like with Adobe tools and every other editor I've used.
It is
Though it doesn't prompt you to recover, so it's easy to miss
@JDługosz If you're interested in messing with procedural texturing I can't recommend watching this talk highly enough: youtube.com/watch?v=kAUmLcXhUj0
@gandalf3 Thanks!
