Sri Yantra

The Sri Yantra is a diagram used as a meditation tool in some Hindu traditions. I don't know of any use in Buddhism. This picture is incomplete (the lotus petals are missing). I built it just as a first exercise in the Java programming language. It turned out to be a nice mathematical puzzle. To get things right requires solving a tenth degree polynomial, if I remember right. I used a simple numerical technique (Newton-Raphson). Here is the source code in Java, for the wildly curious.
