Thanks for posting that. I rarely do any kind of mining technique. Might have to try this!
I'm not sure what I think of it myself yet. I drew it in AutoCAD just to see what it what it would look like & have a plan to start with. I tried it a little later in the evening, & it seemed to work well, but it was a bit disorienting, & I'm really struggling to come up with a pattern to light it with. For now, I'm just throwing lights everywhere, & I've recolored the central shaft, but I think I may have to color code the entrances to the separate directions, & look into the lighting more if I'm going to use it regularly.
