Hi Corribus. Good point. In this version I'm using Caslon for the symbols, a typeface that dates back to the 1700s. The colors are also retro. That's intentional for this version but I'll be looking at alternative typefaces and color choices soon (and have been looking at variations) to tone it down and minimize visual noise. I'm showing this one as is, in-progress, to gather feedback on all points, sooner than later. Thanks for sending that comment.
