Phoenix fractal

Phoenix fractal was discovered by Shigehiro Ushiki; in 1998 in paper published in the 'IEEE Transactions on Circuits and Systems' journal. The Phoenix fractals are modifications of the Mandelbrot and Julia sets. The initial Phoenix fractal formula was z(n+1) = z(n)a + c*z(n) b + p*z(n-1) with the parameters of c=0.5667 and P=-0.5.
