Short answer is, yes, you can convert them to work in Fractint. They are simulating the use of complex numbers using the float data type, so it is confusing. The variables in the Fractint formula parser are complex numbers. A colon needs to be inserted to separate the per pixel initialization from the loop section. The variable z needs to used for the bailout (|z| < 4) to let Fractint work properly. But |z| = fx2 + fy2, so that part is easy. Haven't noodled my through the rest enough to make it make sense. These appear to be similar to the manzpower and julzpower fractal types with the real part of the exponent set to 3, 4, or 5. I could be wrong, having not noodled enough. Jonathan
