Here's something I started on a year or so ago. I have the rough idea down and want to keep the "line art" look, but I'm a complete novice when it comes to working with Illustrator. If someone could help me flesh this out a bit I'd be most appreciative. I'd also like to have an om in the middle, but couldn't get it to look right at all. I do have this in AI and SVG format but this gives an idea of where I'm at.
