That's a good idea to use the SVG! I'm generally in the habit of using PNGs or other rasters for the internet, because really, while most people can see them these days, there are still some browsers that aren't 100% on displaying SVGs. But I think I will take your advice, and use it, in this case.
Not sure about the intersections you mean. The original version is the vertical one on the home page, and I had to sort of re-do it for horizontal display. Now I forgot exactly how I did it the first time. I thought I got everything right, but not surprised if I didn't
Edit
Also, I was just looking at some of the alternate themes. It really looks different on the darker themes, like CC. Also realized I need to do quite a bit of tweaking on some of the alternate themes!
