Persona Charts at Astrodienst
We at Astrodienst have taken up Orban/Zinnel's idea, and can offer you persona charts in various varieties. You can buy persona chart drawings in our shop (only in German), or look at your nine persona charts in the "Extended chart selection" of "Free Horoscopes".
Of course, this concept can be developed further, and some of the more curious astrologers will certainly cast persona charts for Chiron, (both!) Moon's Nodes, ascendants or midheavens.
