Energy Diagrams Development

I started by creating a few energy diagrams like the ones from 'Numerology' by Norman Shine.

The diagrams work by indicating the number of numbers within the persons name by circling the number. For example in the left diagram there's one 8 in the name so only one circle is placed around the 8. This looks interesting, but I'm sure there is much more that can be done with it.
To begin with I simply took away the numbers so that all that is left are the circle patterns. Doing this kind of diagram creates a 'finger print' for the person using their name and could potentially be used in some form of identification.
Going on the idea of identification I thought of a potential problem - if two or more people have the same name then they would have identical patterns. To get around this potential problem I thought that distinctions could be made using colour and/or the thickness of the lines of the circles. In the left example above I've looked at using different colours - the colours were selected from a swatch option in Illustrator. In the right example I have looked at thickening the lines and using completely different colours.

With both I think there is some improvement - personally I prefer the right one for the thickness of the lines, but the left one for the colour choice.
